This beautiful exotic hardwood is ready for your unique woodworking projects! This book matched set has two pieces. One piece is 5/32" thick, while the other is 1/8" tapering down to 1/32" thick. The latter piece would be good for head plates, but because of this set's unique nature they would not be suitable for instrument sides. With the purchase of the board that is 1/32" thick, the second board is free! These pieces are a set and cannot be returned separately.
