If the clip is lost during use, you can use common flat plastic items found around the house to insert it into the groove of the band and assist in pulling it out. Avoid using sharp metal objects to prevent scratching the band. Suitable alternatives include a paper clip, a card, or a toothpick. Make sure to handle the band gently to avoid damaging it. For best results, opt for items that are sturdy yet smooth to ensure a safe and effective disassembly process.
