I'm pretty sure it's described as a display for coins. I have a few of them. There's usually Michael's coupons that can snag these at a discount from there.
Do those channels keep the chips in place? Or can they still easily roll around if you're not careful?
They're only held in place by the lip of tiny shelf and gravity. If they're hanging up, they shouldn't fall out of place, baring something like a slammed door near by.
They do, I did get one where the shelves had been installed "upside down"....so I returned it to the store and got a replacement, but it was pretty funny trying to explain it to the cashier...
They actually explicitly mention chips in the description. Wondering if anyone has ever used these for displaying singles? Seems like it could be a good for a desk (next to the evergreen shuffle stack, of course).
