Review on 🔒 100Pcs Black Silicone Cord Locks for Masks - Adjustable Rope Toggles, Non-Slip Stopper Fixing Buckles, Suitable for Adults and Kids by Doris Tran

These packs (both white and black), which ship quickly, are great for tightening the mask's ear loops unless you're trying to use the included "stealth" loops to secure the Thread loops through the bead. The invisible is too big, it stretches the rubber bead and reduces its holding capacity. A good stiff wire needle threader can work, but a darning needle will also work. Thread a strong thread into the darning needle; Thread a (blunt) needle through the small hole in the bead, leaving a tail; pass the thread through the ear loop; Thread the needle back through the bead, then pull the ear loop with thread through the bead. You can wrap the thread around a pencil or something similar several times so as not to damage the skin when you pull the loop through the bead.
