BetterMaskSeal is a moldable nose strip for a surgical mask that is heat molded to fit any face, using a standard iron for heating the strip. The strip needs to be molded only once and can then be reused after disposing your masks. The resulting fit prevents fogging if you wear glasses and also improves both comfort and protection level of the mask. Perfect gift for friends and family in these times! Suitable for printing only in PLA. - Stay safe and wear a mask! Note, commercial use is not allowed and the concept is patent pending.
