If you've chosen the 'Pets in Names' or 'Way with Words' design this frame style is ideal for the horizontal format because it allows for larger/more letters with less empty space top and bottom. It is very distinctive simply because it's NOT a standard shape.
They're made from recycled polystyrene known as Polcore rather than wood, which you wouldn't know until you picked it up, 20mm wide and 30mm deep. The brushed black coating is beautifully done and gives it a very smart look.
PLEASE NOTE: the frames are fitted with 2mm perspex not glass.
