Review on Cord Locks Silicone Toggles for Drawstrings Elastic Rope - 100PCS (White and Black) by Lori Aguirre

Product is soft and stays in place. Perfectly washed and tumble dried. Great for masks, if your earloop is too big for kids, use it to tighten. There were no instructions or anything to attach the rope to. You must purchase this separately. In a bundle I used the smallest and second to last size hex tool to push the 1/8th rubber through. My 3 and 5 year olds didn't seem to mind wearing it, but they didn't wear the mask for more than an hour. I was afraid it would come off in the wash but no. The second set of homemade masks. First I put an ear loop through and then tied the end so my kids can't pull the clasp out.
