The right period product is not simply the longest or most absorbent option. It is the format, length, cover, and fit that best match your flow, activity, and daily routine.
Founded in Korea in 2002, Yejimiin develops feminine-care products ranging from panty liners and daytime pads to pull-on overnight underwear. Its collections include herbal-inspired Yunseul, slim-profile Pure Slim, organic cotton-cover Organit Daily, and underwear-style overnight protection.
This guide explains what each format is designed to do, translates the supplied feature graphics into practical shopping information, and links directly to every size currently offered by Kim’s Basket.
The problem: one product cannot fit every day
Panty liners, sanitary pads, and disposable period underwear may belong in the same care routine, but they are not interchangeable. Liners are intended for light daily moisture, discharge, spotting, or lighter beginning-and-ending days. Sanitary pads provide a larger absorbent area for menstrual flow.
Length affects coverage rather than automatically determining quality. A shorter pad can feel easier for lighter-flow or active daytime use, while a longer pad provides more front-to-back coverage. Your preferred underwear, movement, and flow can all influence the best fit.
Pull-on overnight underwear surrounds more of the body than an adhesive pad and can be useful when you want a garment-style format for sleep. Because it is worn rather than attached, selecting the package size that follows the manufacturer’s fit guidance is especially important.
The solution: choose format, features, then size
First decide whether you need a liner, menstrual pad, or pull-on overnight product. Next compare the cover and construction details that matter to you. Finally, choose the available length or garment size that provides the coverage and fit you prefer.
Kim’s Basket carries six Yejimiin product lines and thirteen individual size options. Yunseul sanitary pads have three sizes; each of the other five lines has two options. The cards below show the exact count and measurement for every listing.
Meet the six Yejimiin product lines
Yejimiin offers different formats for different moments: full-size sanitary pads for menstrual flow, slim panty liners for light daily coverage, and pull-on period underwear for overnight wear. The six sections below explain the practical differences so you can compare construction, coverage, length, and pack size before choosing.
1. Yunseul Herbal Pure Cotton
Yunseul Herbal Pure Cotton is the full-size sanitary-pad line in Yejimiin’s Korean herbal-inspired collection. It is available in Small 23 cm, Regular 25 cm, and Large 28 cm, making it the broadest length range in this guide.
The supplied botanical artwork identifies five featured plants and their Korean growing regions: Ganghwa mugwort from Ganghwa-gun, Angelica root from Pyeongchang-gun, Houttuynia cordata and motherwort from Jecheon-si, and mint from Goryeong-gun. These details describe the collection concept; they should not be interpreted as medical benefits.
The Yunseul Herbal Pure Cotton pad artwork highlights a soft cotton-touch cover, contoured absorbent core, breathable film, double-layer premium absorbent sheet, and leak-guard line. “Pure Cotton” is the product name; the artwork specifically describes the surface as a cotton-touch cover rather than claiming that every pad component is cotton.
2. Yunseul Herbal Panty Liners
Yunseul Herbal Panty Liners are the lighter-coverage option in the same herbal-inspired collection. They are intended for everyday discharge, light moisture, spotting, or lighter beginning-and-ending period days—not as a substitute for a full-size pad during heavier flow.
The supplied graphic highlights a cotton-touch cover, quick-absorption layer, breathable film, easy one-touch wrapper, and herbal ingredients. Choose Regular 15 cm for the shorter format or Long 17.5 cm for additional front-to-back coverage; both packs contain 20 liners.
3. Pure Slim-Fit
Pure Slim-Fit sanitary pads are the menstrual-flow option in this slim-profile collection. The supplied graphic highlights a slim absorbent layer, secure leak-guard line, soft cotton-touch cover, and a German Dermatest “Excellent” skin-compatibility result. Testing language describes the reported assessment; it does not guarantee that irritation cannot occur.
Choose Regular 25 cm with 18 pads for everyday menstrual coverage or Large 28 cm with 16 pads when you prefer additional front-to-back coverage.
4. Pure Slim Panty Liners
Pure Slim Panty Liners are designed for discreet, light everyday coverage rather than full menstrual flow. The Regular pack contains 52 liners at 15 cm, while the Long pack contains 46 liners at 17.5 cm.
The supplied artwork highlights a 0.7 mm slim profile, breathable film, easy one-touch packaging, cotton-touch cover, and 3D embossing designed to help the liner retain its shape after absorbing discharge.
5. Organit Daily
Organit Daily uses an organic cotton cover—the surface layer designed to contact the body. This wording does not mean that every component inside the finished pad is made from organic cotton.
The supplied artwork shows Organic Blended Content Standard certification number CU822340. It also highlights a Fresh Air-Fit cover designed with a smaller skin-contact area, air channels and a double-layer absorbent core, plus a 360° multi-leak-guard design with front, back, and side barriers.
The Regular option measures 26 cm and contains 16 pads; the Large option measures 29 cm and contains 14 pads. Compare these lengths with your usual underwear and preferred coverage rather than choosing by product name alone.
6. Disposable Overnight Period Underwear
Disposable Overnight Period Underwear is a pull-on, garment-style option for sleep. Unlike an adhesive pad, it provides surrounding coverage and stays in place through the fit of the underwear. It is available in Medium and Large, with four pieces in each pack.
Choose the package size that follows the manufacturer’s fit guidance and feels secure without being uncomfortably tight. The pull-on design can provide added confidence for movement during sleep, but no period product should be described as completely leakproof; changing it when needed remains important.

- Choose the job: Select a liner for light daily moisture, a sanitary pad for menstrual flow, or pull-on underwear for garment-style overnight coverage.
- Compare length and count: Check both the centimetre measurement and the number of pieces, since pack counts vary across sizes.
- Consider the cover: Yunseul and Pure Slim highlight cotton-touch surfaces, while Organit Daily specifically identifies an organic cotton cover.
- Check your comfort: The product should remain secure without rubbing, bunching, shifting, or feeling uncomfortably tight.
Build a practical period-care routine
Keeping more than one format available can make changing flow and daily routines easier to manage. A liner may suit lighter moisture, a regular pad may fit routine daytime use, and a longer pad can provide additional front-to-back coverage when preferred.
Change pads and liners regularly and sooner whenever they feel wet, full, shifted, or uncomfortable. Wash your hands before and after changing, wrap used products, and place them in the trash rather than flushing them.
For disposable overnight period underwear, follow the package fit guidance, put on a fresh piece before sleep, and replace it upon waking or earlier when needed.
Important care note
Follow the manufacturer’s instructions and use the final package as the authority for materials, sizing, changing guidance, cautions, storage, and disposal.
Stop using a product if it feels damaged or uncomfortable. If irritation persists, or if you are concerned about unusual discharge, odor, pain, or menstrual bleeding, seek guidance from a qualified healthcare professional.
These products help manage menstrual flow and everyday moisture; they do not diagnose, treat, cure, or prevent a health condition.
The takeaway
The best Yejimiin option is the one whose format, length, cover, and fit match the day in front of you. Panty liners, menstrual pads, and pull-on overnight underwear each serve a different purpose.
Yunseul provides herbal-inspired cotton-touch pads and liners, Pure Slim focuses on lower-profile formats, Organit Daily uses an organic cotton cover, and disposable overnight underwear offers pull-on coverage in two sizes.
Compare the exact measurements and pack counts before purchasing, then let comfort and the level of coverage you need guide your choice.
