Medical‑Grade Jelly Gel
We adopt premium medical‑grade jelly gel as the core raw material for our bras. Safe, skin‑friendly and non‑irritating, it fully meets high‑standard hygiene requirements. Starting from source material control, we eliminate your concerns about product quality, skin‑sensitivity risks and high return rates, helping you cut after‑sales costs and build long‑term‑stable product reputation for your brand.
Breathable & Hypoallergenic Technology
Our exclusive breathable anti‑sensitive adhesive technology delivers outstanding performance: ✅ No glue‑fall‑off, highly breathable, safe & hypoallergenic, withstands over 50 washes. Compared with ordinary adhesive materials, it effectively reduces skin redness, itching and allergies caused by long‑term wearing. Reliable stickiness stays consistent without slipping during daily activities, even after repeated washing.
We support OEM & ODM customization, welcome global buyers for further technical consultation and sample testing.
