This is a superb cup handmade in Japan by Misa Kumabuchi of Mushimegane Books. A recent piece from her collection, you won't find a more characterful drinking vessel than this.
The glaze itself is something to admire, it comes in a beige colour which is speckled in appearance, giving it a textured look in all shades of light and dark.
Note: These are made by hand so each one may differ slightly from the photo. The handle is a 'pinch handle' and is to be held by pinching instead of hooking your finger inside.Approx Measurements: 5cm height x 10.5cm
