i made this for frozen fish food. place the frozen fish food package (which comes in 8 per pack) sideways into the punch lining up the food bubble with the rounded out end of the cylindrical punch part, then squeeze the handles together to punch out the pellet. assembly should be apparent and super easy. just push the press fit pins into place. there are 2 longer and 1 shorter pins so careful where u place them for proper fit.

i imagine this to be used to punch out other things.
