Purchased new from Sound House. Used it outdoors about twice. Internal dimensions: Width: Approximately 63.5cm Depth: Approximately 30.48cm Height: Approximately 49.53cm The top panel is sturdy, so it's possible to place a combo amp on top of the case and use it like a stage box. Due to the large size, it will be shipped from a business office, etc. Therefore, there may be a delay of 1-2 days from the scheduled shipping date. The item will be shipped as is, wrapped thickly in bubble wrap without being boxed. No price negotiations. Instant purchase OK.
