These are my favorite beads to work with, but if you want to have color patterns appear in the sun then you need to sort them first!
These beads are awesome!!! I made a bracelet with UV beads at school and wanted to get some more beads. I saw these that glow in the dark and react to UV rays. They are great quality and glow VERY brightly, especially after they have just been in the sun - I brought them inside, and they were glowing in a room that wasn't all that dark.
Excellent purchase. Beads did as described; changed color and glow in the dark. I made braclets for end of the school year for ages 4-8 and they loved them. Would by again. Shipped on time.
Really cool beads. They are UV reactive and glow in the dark.
My daughter loves these. They all glow in the dark and also change colors in the sun!

These are so fun for kids of all ages. They glow in the dark and change color in the sun! My kids made all their friends a bracelet. Awesome product!
