HDCRYSTALGIFTS Mini K9 Kristalglas Prisma Kubus, Optisch Glas RGB Dispersie Prisma X-Cube voor Natuurkunde Onderwijs Art Decor Fotografie Rekwisieten, 15*15*15mm

Very small but beautiful. Wasn’t able to see the light fractions being reflected off the floor or wall because of how small it is but it is exactly as described. One thing to be careful though. It’s very fragile. Don’t drop it on hard flooring because it will be chipped. At least that’s what happened to mine. Might have to get a new one.

Just a cool little object to look at and fiddle with. Great colors!

I bought it for my 5 year old grandson. He was thrilled and so was I.

The photos make it look like it's much bigger. You end up paying a lot of money for one single tiny cube. I'm not saying it's not fun to look at, but it's not worth the price.

I like the colors, I thought it was totally clear. But reflects light nicely.
