Urgent and very important question (maybe) Big Bang Theory

Anyone who watches Big Bang Theory..

What are the half a dozen or so coloured things stuck to the side of Howard and Bernadette's fridge? About the size of mugs.

Magnetic cups with coloured foam sleeves, maybe.

Hmm, I see them but can't think what they are.

Must be an easter egg thing as the other fridges are.

Look like magnetic spice jars.

Here you go.
