Acrylic right?

They’re more for display. Three have fallen about 6-7 feet onto the floor without any sort of damage but then again they fell on floor that was carpeted (not very cushiony carpet mind you but it was still enough padding) and my Celestia one fell about 5 feet onto concrete. It didn’t shatter but it has some micro fractures now.
 
The downside is that I don’t have a proper image showing them to scale but they are not regular marble size and are more like baseball-softball size. That size MAY be helping to a degree but I only really meant these to be for display so I wouldn’t try it just in case. The glass I work with is surprisingly tough though and doesn’t break THAT easily if it’s thick enough and depending on what you drop it on. I’ve even dropped vases I was making onto concrete and they didn’t shatter (though that is likely due to being hot and having a tad more yield to it since it’s not a solid crystal yet).

These are quite lovely! I’m tempted to see how they’d do in a downhill race of some sort, haha.
 
Are they tempered to be handled like normal marbles of one wished to, or are they just meant for display?
 
And, just how big are they, actually?

I must say, these are marble-ous.

Thanks. I like to think they are XD
 
I am uploading 6 new ones each day or so, and in total I have about 36 so there’s more…..not all are that great unfortunately due to unforseen complications (mostly with how the colors behaved after being annealed) but I think they are alright.
 
Either way, glad yah like em.

These are…beyond amazing! Keep it up!
