Corda elastica antivento per la regolazione della maschera, per una vestibilità perfetta e confortevole. Ideale per protezione e sicurezza.

This product is good. It does exactly what I thought it would.

They're excellent. I purchased them for my job at a dental clinic. After working long hours, my ears would hurt. These are also useful for hanging my mask when it's removed, providing relief from ear pain!

They're cool.

They looked just like the pictures and are simple to use.
