Collection of NZ wood samples. At wood.treeworkx our selection of wood species is growing all the time. After repeated requests for various species we have made thousands of wood samples compatable with pen blanks. Most typically our samples are 160x22x22mm in size. We offer a random selection of fifteen different native and fifteen NZ grown exotic wood samples. Wood has been named for you. These are packaged in a convenient A5 box for presentation and free shipping within New Zealand.
