Small, traditional, cast iron Japanese Tetsukyusu teapot. Similar to tetsubin but with a glaze inside meaning it is only for steeping tea, NOT for boiling water directly on a heat source.  Features stainless steel steeper, classic "arare" dotted pattern, and foundry mark.  

Approx. 6 ounces.  5" long and 3" high (4.5" with handle). Note: There is a tiny amount of rust on the rim and a small section of the steeper (see photos).  Thanks.
