Help identifying these coconut cups?

I found 6 of these recently at a thrift store... they look very similar to the Ed Langbein (MCM Italy) cups or the Taboo Island coconut, but these have a brown lip with the crackled white glazed interior you get on older ceramics, thinner walls than the Langbeins, and no markings on the bottom at all (which is also more unfinished looking than the above examples). The grooves on the side are pretty deep and rough, probably done with a pottery wire tool versus a fine-tined fork.

They are about 4 inches across and 2.5 inches high on average though the top/lip edges are varied with a wavy line.

I'm guessing they may be cups from a hobbyist mold, possibly. Nothing special I suppose, but... anyone know?

Note also that each cup has identical markings on the bottom (the various dark divots, lines, etc.) and a mold line, so my guess is that they were all probably produced from a mold made from one particular real coconut.

Those coconut mugs could possibly be from Otagiri Manufacturing Company (OMC), a competitor along side Orchids Of Hawaii. Still not 100% sure though.

I've never seen those before. Nice mugs.
