I have decision paralysis, help me out anons.

Wanted to buy cup coasters to comfy-max my morning coffee or tea, but mostly for when guests are over.
Picrel are the options, the first is just cheap felt coasters. Cheap but likely not long-lasting.
Second was my favorite but it's exactly 8cm and my cups are also exactly 8cm in diameter, feels like having a coaster that's precisely the size of the cup might be annoying.
Third is nicely priced, but comes without a holder and it's untreated wood. Then again I could just oil it.
Fourth is nice, but also more expensive than all of the others and the most grandma-core of the bunch.

Which one would (you) get?
