Most are pale off-white, or pale versions of their glow color.Q: Is the sand safe?A: Yes, the chemical compound is completely non-toxic and non-radioactive, unlike the 1930's glow paints, it's about as dangerous as beach sand, meaning you should still avoid eating any or giving it to any small hands that might eat it, but don't worry if a little spills .Package Included:1 Bag x 10g of Super Bright Glow-in-the-Dark Sand ParticlesNO Retail Box.
