For your consideration, please see these individual crab shell serving ramekins made of French white porcelain (unbranded, but could easily be Apilco or Pillivuyt).  Oven safe.   Measures 6" long (from point to point) and 2 5/8" wide, and likely holds appx. 3-4 ounces of crabmeat.  Each shell weighs 5 ounces.  Will be shipped with care via USPS.  Let me know if you have any questions.  Many thanks for looking and happy shopping!

Multiples are available.  1 of the 8 crabs has the tiniest chip on the inside rim of the crab.  Please see all photos, and last photo will show the 8th crab.  It is tiny and hardly visible, and does not detract from the form or function of the shell.
