Due to hygiene and contamination considerations, our floss capsules are specially sealed and cannot be replaced with other dental floss.

We have made great efforts to prevent it from breaking and finally adopted shred-resistant material with high strength and elasticity to reduce the possibility of breaking. However, if the floss encounters something sharp, it still has the possibility of breaking.

In case the floss breaks during use, there is no need to worry, you can continue to use it by tying a knot.

After use, it is recommended to wipe the part that touches the mouth with a tissue. It can be rinsed with water and needs to be wiped dry after rinsing. Do not soak it.

If you want to discard the floss capsule, since it is mainly made of biodegradable plastic, please follow the local garbage disposal regulations to discard it.
