These wooden letters and numbers are great for decorating your walls, office signs, craft projects, party decorations, etc. Created by nature, Baltic Birch will have minor variations of color, grain patterns, and small mineral streaks are typical. Baltic Birch Plywood is generally regarded as higher quality than standard plywood. It is made entirely from birch plies, and unlike regular plywood, it has no softwood or filler plies in the center. The plies are glued together with waterproof glue, and when exterior paint is used, it is suitable for outdoor signs.
