Does anyone know where someone could buy Trumpeter 09811 Display cases in the United States? They are plastic display cases for 1:72 scale tanks and have five cases per package.

Here’s an example of what they are:

I have found them for sale in hobby shops in China, United Kingdom and Australia. But I'd rather not pay for shipping that costs more than the product.

If any of you have purchased these, here are some related questions about these display cases -

Are they decent quality?
Are they the same size/stackable with Dragon display cases?
I'd like to use them for my Forces of Valor and Easy Model Tanks.
Thanks!
