Five Slot Insect Butterfly Mounting Spreading Board, polystyrene Foam, 11 inches Long x 17 inches Wide (28 x 43 cm) - Product Features
- Our board has five grooves measuring from 1/8 (.32cm) to 5/8 (1.6cm) accommodating most specimen sizes on a single board.
- Designed for spreading insect wings prior to mounting. It is ideal for allowing butterfly wings to spread and dry.
- Place a moth, butterfly, or other insect's body in the indentation on the spreading board, and pin a thin strip of paper over each wing to hold them flat until they dry out.
- Deep groves cut into a 1-3/4?-thick (4.4cm)styrofoam block allow for perfect positioning of specimens using any pin length.
- Light weight, sturdy and economical.
