This is an acrylic stand that can hold photos, pictures, etc. By changing the position of the included metal fittings, you can switch from a vertical stand to a horizontal stand. The approximate dimensions are width 23cm and height 30.5cm. Since A4 size will touch the metal fittings at the four corners, you will need to insert pictures or photos that are slightly smaller than A4 size or have their corners cut. It was used once at a business meeting and has been stored since then. There are no noticeable stains or damage, but please understand that it is used. Transparent acrylic wall-mounted photo frame with metal holders. - Material: Acrylic - Color: Transparent - Mounting Type: Wall-mounted - Holder Type: Metal rods Thank you for viewing.
