What are you knowingly purchasing or consuming that is not vegan?

I’m really curious to know are there any things that you purchase or consume which are knowingly not vegan?

Just as an example I had to buy new tyres for my car which when doing some research I could buy vegan tyres but would have to change my wheel size and buy new wheels also And the safety rating was far inferior compared to a non-vegan counterpart tyre.

for consumption the only knowingly thing that I’ve done is had a Covid vaccine which would definitely not be classed as vegan due to testing and manufacturing.

Really curious if anything obscure pops up and might help inform people of unusual things which aren’t actually vegan 🌱
