INERTIA Premium Period Pads are designed by female scientists who believe your period care should be as smart as it is safe.

No irritation. No microplastics. Just science-backed care that works.

2. Peel off the adhesive backing.

Are You Using Truly Organic Pads?
Most likely, only the top layer is organic.

Many pads claim to be organic,
but most only apply it to the top sheet.

At INERTIA, we go deeper.
Every layer that touches your body is made from certified organic materials, and even our absorbent core is plant-based.

This means no chlorine, no plastic-based SAPs, no greenwashing.

Best organic pad I’ve tried

I’ve been using this brand for a while now, even though I originally thought it was a bit pricey. But honestly it’s worth it!! This is the only pad that doesn’t make me feel heavy (like that subtle aching, if you know what I mean) or damp down there. I think it might be because it doesn’t have microplastics? I’ve tried other “organic” pads from cvs, but most of them only use organic cotton on the top layer, which doesn’t really help… These actually feel breathable and super comfortable. I feel clean and dry all day, and that peace of mind is totally worth the extra cost. I’ll keep coming back to it - highly recommend!

Surprisingly Comfortable and Thoughtfully Designed!

I didn’t expect to love this pad so much, but INERTIA really impressed me. First off, the packaging is beautiful—it actually made me feel like I was opening something special, not just another box of pads. The design is sleek and minimal, and the materials feel super soft and gentle on the skin.I especially appreciate that it’s made with organic cotton, and you can really tell the difference. No irritation, no weird plasticky feeling—just clean, breathable comfort all day. The leak and odor lock technology works way better than I expected for a regular pad.Also, the fact that it’s only 10 in a box makes it great for trying out or keeping in your bag just in case. Definitely going to repurchase and try their other absorbency levels!

Safe, Comfortable Pads You Can Trust

INERTIA is a sanitary pad brand created by Korean female scientists. It’s made from 100% pure cotton, so it’s gentle on the skin and there’s no need to worry about any odor.After trying it, I found that it has excellent absorption, so I didn’t have to worry about leaks at all. It has also passed sensitive skin tests by Germany’s Dermatest, which makes me feel even more confident using it.The sizes are clearly labeled, making it easy to choose the right one, and it’s convenient to store neatly in its case. I highly recommend it for anyone looking for a safe, comfortable, and worry-free pad!

As a total pad nomad, this one is a game changer!

I only care about two things when it comes to pads: softness and absorbency. And let me tell you—this one is unbelievably soft. Like, next-level soft. I was honestly shocked the first time I used it. And yes, it absorbs really well too. If you’ve been bouncing between brands like I have, you NEED to try this. Highly, highly recommend! I opened one pad to show its soft texture!

Organic cotton pad for women ❤️

In Korea, inner beauty is in vogue these days.👑 They put health first before women who take care of their appearance.So I always choose sanitary pads carefully as they touch important parts of a woman, so I tried this brand this time.In the United States, there were a lot of sanitary pads made of vinyl, so I felt very uncomfortable on my skin. I've tried a variety of brands, but in the end, I've never felt as satisfied as the sanitary pads I used in Korea.So I thought I could buy a Korean sanitary napkin on Amazon, so I tried it without worrying.I studied for 30,000 hours, 387 studies! 8 weeks of clinical trials, 13 reviews. It was unbelievable.When I took it out of the box, first of all, the meticulous and clean packaging already gave me trust.When I bought sanitary pads in the U.S., there were some products that were not packaged one by one and just came in a box! This sanitary pad felt good from the moment I took it out.This brand is a good and warm-hearted company that has signed a regular donation agreement with the Children's Welfare Association for sanitary pads.Organic sanitary pads are microplastic-free! It is a sanitary pad that uses 100% organic pure cotton to the wings and inside.There are many places that usually use pure cotton and promote it as organic, but the brand made it without overlooking any small parts except for all the harmful ingredients for women's health.And it is said that every layer is made of Bio-based material, from the cover and film of sanitary napkins that are 100% decomposed in nature. These days, when plastic is a problem, this brand that even thinks about the environment... I think it's so good.The absorption was very good and the surface was so soft that I didn't feel any discomfort at all. Many women tried this brand and thought, "I hope you don't feel uncomfortable using sanitary pads anymore." It was uncomfortable to bring sanitary pads from Korea every time, but now I'm going to use this product only. If I have female friends, I really want to buy it and give it as a gift!
