Selected Triple A Grade balsa wood blocks, sheets, and strips, cut to very close tolerances. Sizes listed are for ?" scale models. 36" standard lengths unless otherwise specified. Use for any type of model building, especially aircraft, architectural, or engineering models. Balsa wood is light and soft but very strong.
