this is a frozen fish food punch i designed to punch out the complete frozen fish food tabs out with just one punch. it also has a bottom receptacle that can act as a container to keep the tablets separated until needed. just keep it all together an if need place rubber band around the whole thing. i made one and i just want to say that this works awesome.
