Funny little pipe

Bought this unsmoked 60's pipe in the pot shape from Ebay. Took me some time to get it 'cause the post had sorted it wrong for me.
When I finally got to pick it up the package was light as a feather. Really funny! When I pulled it out I thought: "What is this! For ants...?"

It weighs 14 grams. The chamber is 15 mm wide and some 20 mm deep.
I think I may have FINALLY gotten my "lunch break pipe" ;D
