Bags?

[Letsplayforfun]

Maybe i missed them, but i can't seem to find containers in EfUA.

Unless it's voluntary, it'd be appreciated to have them more readily available, as they are pretty handy.

[Listen in Silence]

They exist alright, they are even sold by a merchant.

[lovethesuit]

Most merchants carry them actually. You shouldn't have to go far.

Yeah, well a bunch of errors showed up on items that were in my bag during a fugue scene and the bag was gone while the things in the bag were still around when I awoke.  
 
But yeah, you can find bags from NPC merchants.
