All frames, passepartouts and glass panes are of the highest quality. The wooden frames were cleanly processed and joined at the back. The passepartouts are 2mm thick, professionally processed and frame the picture cleanly and neatly. 40 x 30cm and 30 x 20cm picture frames are delivered with real glass. For the sizes 60 x 40cm and 80 x 60cm we have chosen high-quality 2mm thick acrylic glass of quality level A. This quality level of acrylic glass is in no way inferior to conventional glass. It does not yellow and does not become milky when exposed to UV radiation and other environmental influences. Mainly we have chosen this glass for the larger frames to reduce transport damage to ?zero? On the back of each frame there are hangers for horizontal or vertical suspension.
