This is the "Skip Carry M" small animal and bird carrier from SANKO (Sanko Shoji). It's a lightweight and simple carrier, convenient for transporting hamsters and birds. The tray is deep, and by using plenty of bedding, you can reduce vibrations during transport. The mesh part and tray are easily removable, making cleaning simple. It comes with one fixed food dish and one perch for birds. Width: Approximately 31.5cm (or approximately 31.0cm) Depth: Approximately 21.5cm (or approximately 20.8cm) Height: Approximately 23cm (or approximately 20.5cm) There may be slight differences depending on the manufacturer's official information or sales sites, but it generally falls within the above range. Thank you for viewing.
