Many collectors (of a great many things) really love the Detolf display case from Ikea. They’re sleek, elegant, and affordable. The simplicity of the design makes for a great way to display your collectibles without detracting from them.
I really like adding lighting. Unfortunately, the options from Ikea are limited. A simple “hockey puck” style light in the top of the case is ok, but the light doesn’t really make it all the way down through the case. I’ve come up with an affordable alternative that gives you great light throughout the case, for about $15.00 per case.
