For setting heights for labels and specimens. Provides a neat-looking finish to your insect collection. Pinning blocks ensure that all labels, and all insects are set at uniform heights, for a professional finish to your display. It also makes it easier to read the labels - the eye follows the neat, straight line.
Pinning blocks come in two varieties: 3 step and 5 step. The 5 step block offers more options for heights. However, the 3 step is generally sufficient for most collections.
Note: pinning blocks typically come with multiple holes per step. Over a length of time (and multiple pinnings), a hole can become wider, causing some loss of the "neatness factor". Damage one hole, move on to the next. Frugality at its finest!
Hole depths are 10, 15, 20, 25 and 30mm.
