As you can probably guess from the subject line, I collect Nendoroids. The W3.9" x H3.9" x D3.9" size case is perfect for if you want to put one special Nendoroid on display. I'd just be sure to measure the Nendoroid's dimensions while you have it in it's desired display pose before you purchase this case. As the dimensions indicate: there's not a lot of breathing room for a Nendoroid with any large accessories. The display case is very sturdy though and is clearly well crafted. I'd place it in the "good buy" column.
