These are adorable. Scottish brownie, good luck gnomes. I purchased them for my children while I was working in the UK and Scotland. These are 20 years old. They appear to be some kind of pewter or silver metal. But I am unsure. May holds a faux emerald. In the brown he stands approximately 2 inches tall. Each brownie comes with his acrylic case (shows some storage wear), and description of the Scottish folklore around the brownie on a gold sticker in the back. I believe these were meant to be stuck on your dashboard in the UK or Scotland. These Brownies are a little cheeky, as you can see this one is scratching his cheek and has pulled up his kilt to do so.
