Artificial inseminators for dog-breeding?

I was also thinking they might be something for horny bitches.

nope nope

They certainly look like medical devices. Although they could be ceramic. Which would be an insulator, or something to conduct heat. We're assuming they go inside something, but maybe they don't. Maybe they heat up and are used to shape the outside of another object. A sculpting tool of some kind. Or... they are decorative ceramic handles, knobs, or pulleys for vintage furniture, or appliances.

Heat sealer probes for the balloon seams, perhaps? Or hot "knives" for working with nylon?

maybe some type of "valve stem"?

You're all warm-ish. I feel certain you'll never guess the actual purpose of these objects. I'll give a couple more clues. They are ceramic. They are a set. They are functional, not decorative. Not medical.

Utensils to help make balloon animals?

We have a Bingo! Congratulations Spexxvet, you're a winner!

I am surprised, though I shouldn't be, having experienced the collective and eclectic wisdom down here in the cellar.

These are latex balloon molds. You dip them into the liquid latex and when the rubber has cured, peel the balloon off. Now you'll probably recognize some of the shapes, no?

Nice work Spexxvet!

Ah... the classic hot-dog bun, chess piece, and anal beads.

Thank you ladies and gentlemen, thank you veramuch.

One is obviously the orange juicer balloon. I wanna know what the one dead center is - it's split in two at the top.

Bunny ears? Mickey Mouse?

edit:

Like these, p'raps?

Probably Mickey.

So there's no artistry to these balloons, you just blow 'em up, and WYSIWYG ???
