I asked the company that manufactures them, they said they didn’t know.

Does anyone know the sizes? I ask because the set is not available in the UK. Flying it over the Atlantic seems ridonkulous when I could just buy some o rings here.

Based on the photo in the question the big O ring is 12 mm outside to outside. The O ring rubber is 2 mm thick.

Googling tells me:

O-rings made from high quality buna-nitrile (BN70) rubber with a durometer rating of 70.

This is proportional to the inventory sticker being 12.0mm high as per all the ones I found in my house.

There appear to be two other sizes in the bag as well, one smaller and one thicker like a tap washer.

Own work

Given this bag of parts is $3.95 USD from several LBS and from Amazon its hardly worth messing about. If the freight is too much, ask for an envelope not a parcel or order more things to make it worthwhile.
