This frame is made from thin aluminium profile in black color suitable for A3 29.7×42 or any poster of that size. Aluminium frames have a minimal modern style and usually are thinner than wood frames.
The frame also features high-definition acrylic glass with a protective film on both sides, mdf back, wall mounting hooks (horizontal and vertical) and turn tabs for easy opening. For more protection during shipping the frame comes packed in aeroplast and a hard cardboard box.
It’s really easy to place your certificate. You simply need to turn the nail tabs, remove the back and acrylic glass or glass (remove the protective film), insert your certificate and close the frame again.
