I was given a puck of Caswell-Massey shaving soap in an unfinished wooden bowl. I promptly lost the top. Hated the soap, but when it was done, I kept the bowl -- now 15 years old. I keep my puck of Trumper's Rose in it now (I was lucky and got a good puck) and I'll replace it with something else, probably TFS Bergamot Neroli.
But the bowl I have ignored, never really dried it, never polished it. Now it is warped, bleached, with a nice crack across it. I love it like this, very wabi-sabi.
