Review on 🎄 4 Pack Light up Tinsel Necklaces and Headbands: Colorful LED Glow Bulbs, 6 Flashing Modes - Perfect Christmas Party Supplies and Gifts for Kids and Adults by April Knowles

They were perfect for our school parade and the kids loved them. There are multiple settings (blink, flicker, freeze) that can be selected by repeatedly pressing the button, and they're all a lot of fun. Can't comment on durability as we used them once and the kids took them home but hopefully they can use them again next year. My only complaint was with the over-packaging; Each chain is wrapped in plastic. I understand you need to keep them separate so they don't get tangled, but a plastic loop or zip tie would do the same thing, and I wouldn't have to fill the entire bin with used plastic bags.
