This is a Eurorack case for modular synthesizers from vivicat green. When listing this item, I confirmed that it powers on and functions correctly by connecting my own modules. Included accessories are the lid, power adapter, M2.5 screws, and M2.5 washers. The label indicates 30 screws are included, and I don't believe any are missing, but please understand if there are any shortages. I'm also including some hand-tightening screws as a bonus, but their precision is not very good.
