Nylon Elastic for ear loops on masks - flat or round, these elastics are amazingly soft, breathable, durable & restore to original length after stretching.
Flat Elastic Size: about 2.5~3mm wide, 1mm thick
Round Elastic Size: about 2mm diameter
Please note - the flat elastic kind of rolls in on itself so when you receive it, you may think it is the round one sent by accident, but it is actually called 'flat'. Why? Who knows, but it's great stuff, whichever one you buy!
