Review on Neon Light Elastic 6-Pack Bow Scrunchies for Girls - Cute Chiffon Hair Accessories, Ponytail Holders, 🎀 Scarf Hair Ties for Women - Glow in the Dark Party Favors Supplies, Perfect for Birthdays, Halloween, Christmas by Holly Smith

I didn't like them at first because the cables and the two batteries in the rubber band make it difficult to manoeuvre. However, after trying them, I think they're cool. They're great for holiday parties or just to wear in my hair while I'm walking around at night. There are six ponytail elastics and each has two battery packs with wires sewn into the holder. To work I had to pull two paper plugs out of the battery. Please note that this has to be done blindly as no outside access is possible. To do this, I had to probe the material. I also had to fumble for and press the buttons on the battery pack to turn it on. There are three light modes: steady, weak flashing and fast flashing. The current price of $15.98 is $2.66 each. I have no idea how long the batteries will last. However, since the block is sewn into the hairband, they cannot be interchanged.
