The different colors glow in the dark with different intensity- could be a let down for some people but I found it a pleasant surprise! The lightest color / white glows the brightest, the blue the least but I also might have needed to charge it up more.
I've had a cricut for years and that's what I used to cut this- it's an absolute dream. Cuts perfect on the "puff vinyl" setting, is the easiest weed I have ever encountered even for tiny details, and it sets in one press.
I haven't washed the glow in the dark yet, but the solid black I've sent through the wash 3 times and through the dryer and it's holding like I just ironed it on.
