I have 20 ADC-001 carded action figure display case available for sale.
I bought them for a show I did back in 2011, you can see them here:

After the show they went back into the shipping cases and outer cases and have been in storage since.
I recently graded a large chunk of my collection so I no longer need them.
They are pretty much as new but may have the odd mark here and there.
I'd prefer to sell them in bulk and I have priced them as follows.
singles - £9
x10 - £80
x20 - £150
Cost would be plus shipping but I am based in Leeds, so pick-up is an option.
Shout me if you have any questions
