Thank you for viewing. I intended to use this as a case for a microphone collection, but I only took it outside once (indoors). It can hold about 8 Shure microphones. When the lid is closed, the microphones are securely held in place by the urethane foam, so they don't move around inside. You can place 57s and 58s vertically, but larger microphones like 87s will need to be placed diagonally to fit. There is a Beyerdynamic logo, but it's a sticker. External dimensions: Approximately 54cm x 20cm x 11cm
