The Dungeon Crawler Carl series by Matt Dinniman. Great story, easy reading, relatable characters, and soon to be made into a series. There are 7 books so far, but rumors say there might be up to 10 eventually.

I would suggest washing them first, but you definitely can. I have 00 plugs and have lost the o-rings on them more than once … and the hardware store has been great for replacements. Just make sure that you get the right size.
