Our lace melt bands are basically elastic bands. However, they have Velcro in the back, which means you can adjust them to fit the size of your head to where it's not too tight. I don't recommend wearing this every day. These are only needed to remelt the lace, touch it up, and workout. Also, for my people who sweat a lot or just if the lace starts to lift. Just put your lace band on and melt that lace right back in. They also keep your baby hairs in place. If you want to install your own wig or others, I highly recommend getting one!
