I loved the idea of the mini pop tunes with lights , was super happy about it until I realized that there were a couple of them that weren’t as bright as the others and one of them didn’t work . They are good for goody bags but just have to keep in mind not all of them might be as vibrant as the others or some will not work . Hope this worksThese are very cool I got these to put in my daughters host/gift bags for her guests at her birthday party and everyone loved them.They’re really fun and easy to use we actually had leftovers and I’m finding them all over the house but my kids love them as well and I highly recommend them it’s a great price and if you’re looking for something whether it’s for gift bags for Christmas goodies or any type of goodie bag I think that these or something you should add in.I hope this review is helpful.Best party favor ever! These pop fidget tubes are filled with LED lights and are the neatest glow sticks ever!They have an on/off switch which make them reusable! Not like the one-time use light sticks! These continue to glow all night long and the kids got to take them home for more fun!The box contains 30 tubes in a variety of colors. Not only are the tubes different colors but so are the LED lights! And the adults had as much fun playing with them as the kids!We shaped them into letters, we decorated the party table, we stretched them out and swung them around! Perfect for our dance party! They can be stretched from 5.5” up to 15.5”.Each tube has LED lights that have three different modes. Just continue pressing the on/off button to get the different effects.
