✨ This is a white frame with a glass plate, used once. Outer dimensions: 560mm wide, 440mm high Inner dimensions: 510mm wide, 390mm high I put in a Japanese domestic size F4 (333 x 242) photo, with a cutout (325 x 234). It can fit up to F6 size according to Seikaido's canvas dimensions. F4 size oil painting canvases are thick, so some adjustments are needed. I've included photos of recommended canvases in the third image (the ones in the vinyl)! These fit perfectly (one unbranded one is included as a free gift). Rowney canvases are slightly larger, so you'll need to trim the backing board, but the image quality is good. Thank you! ^_^ ‼️
