Cornish Cuttlefish bones for budgies and other aviary birds (Summertown OX2)

Cornish cuttlefish as seen and a source of calcium to help keep birds' eggshells strong. These are untreated so you may wish to clean/ wash or other before giving them to your birds. [See internet search for details.]

The number is about 6 and are about 14 cm long apart from any broken ones. I've got 6 more and will be happy to bunch the lot together.
Please let me know details for collection. They can be left out for your convenient collection.
