The Spill & Refill Coffee Mug Fidget is a novelty mug made up of two parts: a white coffee mug and a brown twisty coffee insert. The insert screws into the mug, and the twisty action creates the spill-and-refill effect that gives this piece its name. At a glance it looks like an ordinary cup of coffee, which is exactly what makes it such a fun surprise on a desk or kitchen table.
Screw the insert into the mug without over-tightening it, and it is ready to twist, fidget with and show off. It is a light-hearted prank piece for coffee lovers, a playful desk companion for fidget fans, and an easy conversation starter when friends or colleagues spot it.
