Trigon Bulletin Board is dual-purpose, with both a bulletin and magnet board, creating a beautiful and comfortable resting place for your photos and notes. Trigon is physically attractive and a contemporary addition to any space, through its sleek, geometric patterning. The top layer is a metal panel with a perforated pattern on it. Behind this panel is EVA foam, so you can either hang notes and photos on it, using push pins or magnets, which come with the board.
