My Desk Calendar--Shells in Acrylic? By Nichols Products

Some of my favorite silly things to collect are items inside acrylic or resin. Never really knew what to call them. Anyway, this is my desk calendar that I absolutely love. Got the teeniest little seahorse in it. The calendar roller is maybe brass. Anyone help me out with materials so I know what to call my collectibles? :)

The last photo shows what the calendar sits with--my favorite pencil and my little Blue Mountain elephant that I just got for a couple of bucks. Never heard of Blue Mountain until him. Now I have something else I want to collect. It never ends.
