100 Pieces Colorful Glass Marbles Glow in The Dark Multi-Color Luminous Glowing Glass Marbles for Marble Games DIY and Home Decor

If these others have some that don't glow, then they have chosen the sets that are just colored marbles.Look at what you are choosing. They clearly tell you which are the glowing oneSmall marble size but they DO glow! I have them in a 1 Liter jar and half sized one too. They do glow if you use sunlight, UV light or another. I love them and bought even more for my other jars too!

I love the variety of colors, they work perfectly for my project.

They don’t glow in the dark. You only receive about 3/4 of a cup of marbles. Very small. They are definitely overpriced for the quality and quantity received. Would not recommend.

These marbles were much smaller than i anticipated. I was expecting a bag of common sized marbles so we could use them in the marble run machine ( it would have looked so cool in the dark!) But they are too small. Still cool, though! The glow lasts a good while.

They are only half the size of an actual marble. They do glow very good.

I only gave them three stars because I actually like the fact that they’re tiny but they didn’t advertise tiny and they DONT GLOW.. not worth my money but I kept them out of laziness to return them

Great price

They do glow and bright when you use a uv light to activate them the longer you hold it on them the brighter they will be and longer they will glow plus you don't need total darkness.
