Don't want a piece of jewellery with a molecule on it? Here's the option to purchase a molecule keyring instead. Chose from our wide selection of molecules and have them put on a silver keyring clip. Will make a great gift.


The molecules will be printed slightly smaller but thicker than the necklace molecules, making them sturdier.


The keyrings are printed on a 3d printer using a plant based polymer called PLA. This particular polymer has wood fibres in it so the printed piece looks and feels like wood.

Molecule 3d Printed Keyring

  • Wood fibre plant based poylmer called PLA. Silver plated chain with clasp.

  • This necklace comes packaged plastic free in a brown craft paper pillow box, which has been hand stamped with the word OXYTOCIN. The packaging will also include a short decription of the hormone, making it a thoughtful and also educational gift.
