There are several carbons that were partially used and stored in Ziploc bags. I was planning to dispose of them, but I'll give them away if anyone can use them.

I gave up on Mercari's identity verification because it kept giving me errors. Due to long-term storage, used condition, and the fact that the items have been handled by people, as well as recent news about Mercari return scams, returns are not accepted. I would like to sell to those who understand this.
