What are these objects and why have I kept them?

[GlitterBiscuits]

I cleared out the kitchen junk drawer, if the photo attaches you can see that I have 2 matching white plastic circles.
What are they? I have no idea but the junk drawer is home to
' I might need that later' things.

Are they spare parts for a roller blind?

Do the little knobby things on the outside turn? Is there anything on the inside of the knobby thing?

Vertical blind fittings???

My house is full of shit like that. I never find out what they are until after I've chucked them and need one.

The little knobbly bits don't move, the inside is smooth and although it looks as if there are 2 sections on each ring it appears to be one moulded piece of plastic

Some weird S&M bands for your dh's testicles?

Napkin rings?

Bits for the back of a washing machine?

I second napkin rings!

The bottom one is a tape measure

Those knobby things look like hooks for a cage. Water bottle holder??

Burger shapers?

I third napkin rings 😁

I thought a tape measure...duh.
Am very tired.

It's a whatchermacallit. You should keep them for when you use your thingummybobs.

You’re completely wrong. It’s a doodah for the whatsit.

ankle monitors

you kept them as a reminder to never ever steal carrots again!

The guaranteed way to find out what they are is to bin them.
The morning after the bins are collected something will break and you’ll realise how they will be the only way to fix it

Oh I have some of these too! I think they might be something to do with the washing machine. Maybe?

You have to keep them when you move house in case they’re for something you’re taking with you. Eventually you have a drawer full of doodads.

I had something similar you use them to stack two Tins of food on top of each other. 2.5inchs is worth of time right?
