Porcelain mortars and pestles. Great heavy duty mortars, with sides that are easily 5/16" thick on the smaller ones, and up to 1/2" on the larger. The mortars are glazed outside, but rough inside, the better to grind, and have a pouring lip. The business ends of the pestles are unglazed, while the shafts are glazed. Very functional, very good looking!! So grind your own spices or lab concoctions as you prefer. You get a mortar and pestle as a single order.

The non-human set of (13) includes a marmoset, frontosa cichlid, green tree python, veiled chameleon, dwarf crocodile eggs, baby kangaroo, red-tailed hawk (oddly flamingo-like), sunfish, baby iguana, rattlesnake, box turtle, leaf frog, and a European rabbit which we think is particularly interesting.
