I initially bought a big pack of various fidget toys for my classroom treasure box. Turns out I love them more than the kids do. These are so much fun and there’s so many cool shapes to make. I didn’t even realize that they glowed. I highly recommend these to anyone.My son loves these I thought you would have broke by now but the are surprisingly strongNot too sturdy and doesn't really glow so much in the dark as they make it seem. You need a black light.I bought a set of non glow clickies (my term for them) after I found myself mindlessly playing with an extremely old set I had from a VERY long time ago. The strip I had been playing with had nearly worn out and I found a set of non clicky for cheap here on amazon. I really enjoyed them so I figured well these glowing ones look neat and I might like seeing them at night on my desk. Well first off - these only click in one direction (people who fiddle with these will understand) and there is no glow in the dark that I could see. I have purchased more of the no glowing ones so I have a supply to fiddle with for years to come.The kids I babysit loves to put the wacky tracks together and see how long they are.Can form these into perfect circles to make a bracelet/anklet OR they snap into place into right-angles to form geometric shapes. You can make anything you want with these--mail holder, pencil box, wacky glasses, etc. Great fidget toy for work or home office.Great value and very well made. Good color assortmentMy son gets a kick out of these, brings them to us to combine. We only give him a couple at a time but he plays with them a bunch. A bit clicks the night I didn't realize he brought them to bed bit that is on me.
