I purchased this temporary picture frame from Maruni Gakubuchi Gazai-ten. For F40 size. MRN-A4106, black. It's an ultra-slim 3mm wide aluminum frame. Purchased in 2022. Unopened, brand new. I'm selling it because I didn't end up using it. I will ship it in the original box it was sent to me in. Temporary frame, exhibition frame, frame for competitions. *Frame only*
