Using glass slides is by far the easiest and fastest way to get perfect butterfly mounts. It is the main method we now use at Little Caterpillar. Each slide is professionally cut with grounded edges for safe handling. Greatly reduces the amount of pins you need for mounting and they will LAST FOREVER!
Includes 6 plates of glass (spreading board not included). Choose between 1 ½" x 2 ½" plates for smaller butterflies, 2"x3" plates, perfect for most average butterflies, or 3"x5" plates which can be used for larger butterflies such as birdwings and large swallowtails.
We cut and sand all of our glass by hand, so there may be slight variations in sizing.
