Oh, my... this is adorable! A tiny resin teapot (lid is removable) that looks like it's made from a pumpkin!
Approx 16mm diameter x 16mm tall (including the stem on top). Including the handle and spout, it's 30mm wide.
This item is in Dollhouse 1:12 Scale.
Also shown below in Teri Calia's Halloween Tea and Treats Shadowbox. Teri even made the tiny green tendrils and leaves on the pumpkin.
