Muffins! Muffins muffins muffins. Muffins, muffins. Muffins. Sorry! But it's a tie bar, with very happy bubbles on it. It matches the Derptie very well, but seems to prefer the Whoovestie for some reason. If need be though, you can wear it with any tie you've got.
Gold and nickel plated, it clips onto your tie, and holds it to your shirt. It is about 2.2" long, and will fit most any tie.
