Our slats are milled from 3-5 year old 5" Moso bamboo. A cut and finished flat side allows them to be easily attached to walls and ceilings with nails, screws, or glue. The opposite side preserves the slight curve of a bamboo pole, as well as its slightly waxy texture and protruding nodes. Slats are available in two colors, "natural" and mahogany. 1 3/4 in. wide (with a variance of +/- 1/32"), 6 ft. long, and approximately 1/4 in. thick.
