Modern wall decor available in three types of wood. Works great with wall collages. 1/4" thick. Approx 15.5"x3.5". No hanging device included. Hanging/mounting with double sided mounting tape suggested. Made from real maple wood, in some cases (depending on color as well) where a wood knot or wood grain may be visible, this DOES NOT mean defective, it's simply a natural occurrence in the wood.
