Collectors use Insect Pinning Block in the pinning process for the purpose of placing labels and specimens at the same vertical level on each pin to make collections uniform in appearance. Place the label or insect on the pin and then push the pin into the hole in one of the three block levels until it stops. This traditional, three-step style pinning block is made of hardwood, with pin holes set at 23mm, 12mm, and 7mm.

Dimensions 3x1x1 inches.
