This is a Revomax water bottle featuring the Mitsubishi Electric MELSEC iQ-F series logo. I obtained it at an event, and the reason it doesn't have a box is that I took it out intending to use it and stored it in a cupboard, but never actually used it. It's too large for me and I find it difficult to use, so I've decided to sell it. Although it's unused, it has been taken out of the box and stored, so I would appreciate it if you could understand the condition.
