These are custom 3D printed with a biodegradable PLA plastic with 100% infill (it is solid/not partially hollow). Choose your own custom color combinations – Choose from Black, Grey, White, Light Pink, Red, Orange, Gold, Bright Yellow, Bright Green, Forest Green, Blue and Light Purple.
I use a Bones Reds precision skateboard bearing for the center, creating longer spin times. Additional regular bearings are used as counterweights.
These fidget toys will keep you entertained for hours!
