Stabilized Curly Acacia

Golden Acacia: Acacia Magnium: Nearly identical to koa in its properties, Golden acacia is a fine grained, highly chatoyent acacia that works and finishes very similarly to koa or tasmanian blackwood. After finishing, layers of oil finish will enhance curl and darken the color.

High Mountain Acacia: Acacia Confusa: Also known as Formosan koa or High Mountain Acacia, is significantly denser than Acacia magnium, koa or Tasmanian blackwood. It's density lies midway between ringed gidgee and koa.
