ZipString Luma - The Patented Glow-in-The-Dark Toy That Flies a Loop of String, Creates Endless Shapes and Tricks Built-in LED for Glowing Fun. Perfect STEM Gift for Kids & Adults. Wonderment Awaits

Great toy. I got these for my 2 year old and 4 year old grand sons, and they LOVE THEM!!!! They do tangle fairly easily, but with an adult standing by to untangle, they provide a lot of fun. I would buy them again!

Fun gift for my son — and husband! The item comes with 3-4 strings that glow-in-the-dark (with a blacklight on the device). Rechargeable, easy to use. I’m a little concerned the strings may wear over time but so far it’s been really fun!

I just gave this to my 10 year old son. It was a HUGE hit. Fun, addictive. It's just cool. I'm not sure how else to describe it. I may end up buying one for myself as I want to play with it too. I'd give it 4.5 stars (but I'll round up to 5) as the only issues I'm feeling are (1) the string can tangle quickly, which I do understand that failure when playing with this thing makes when you master it it better, but I wish it was a little easier to unknot/untangle; (2) it is a little louder than what I'd like; and (3) I wish there were ties included for the strings or some sort of included string organization... The strings didn't come with any rubber bands or twist ties, but the short charging cable did lol.

The highlight of Christmas! I bought one for each of my girls and it was the highlight of our Christmas. It works great! The battery life last FOREVER! Easy to use for my 6 year old. My girls love making it do all the tricks. Perfect fun for kids at any age. The color of the strings is perfect! Even adults will love it!

We love this product! However, we bought 2 and one must have a short in the button area as it shuts off while holding the button after less than 1 second and then eventually completely stopped working within a few minutes. The one that does work is so fun and the glow feature is awesome!

This was the hit of Christmas 2025! The 10 year old recipient thought this was so cool and so did all the adults. Came with several other strings and while I think $30 is a little high for what it is, it was worth it to see him that happy. The Glow in the Dark feature is very impressive and this was an easy item for a 10 year old to quickly master - just push the button and move your hand around. Doesn't get tangled up unless you try.

This toy is awesome! My son loves it. It comes with several different string sizes and colors. Only the white ones actually glow. It's very easy to set up the strings and use. It's a rechargeable battery, which is great. The only issue is you will be untangling the string quite a bit when the younger kids are learning to use it, so definitely start them out with the short string. The longer strings are best suited for outdoor use, unless you have a huge room to use it.

This is a neat device that my son loves. It seems to be of good quality and comes with an assortment of different sized and colored strings. Lots of fun for the kids. The strings are hard to keep untangled but overall it’s a fun device that was cheap in price and offers entertainment.

Great little toy, highly entertaining. Battery seems to last ages. The longer strings need to be in a big room or outside. Glow in the dark feature works really well at night. Lots of fun and easy to use.

6 and 9 year old LOVED it

My little guy loves this, so much fun!

My son loved this.

These are far more entertaining then they have any business being. Purchased for kids birthday party and used long afterwards by the adults in the house :D
