The thread retains its strength and appearance even after repeated washings, withstands mechanical stress and does not lose color when exposed to sunlight.

5. Environmentally friendly and safe
The OEKO-TEX certificate guarantees the absence of harmful substances and the safety of the threads when used in clothing, including children’s and medical.
