Ciseaux, longueur 10 cm, pliants

Folding scissors are especially useful when traveling. They can be folded, don't take up much space, and most importantly, you won't hurt yourself. There is a small hole (2.5x5 mm) at both ends of the handle through which you can thread a string, chain, or small carabiner.

The scissors measure 2.5 x 8.7 cm when folded.
