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, 20, and 25mm.
