Although the looks of the Crumar Seven suggest that it was built in a flight case, the suitcase it is in is mainly made for those looks. The Seven should be treated for transport like any other digital piano.

The SPT-77-BK is a trolley bag for transport and to protect the Crumar Seven.

Disclaimer: The wheels are designed for transport on smooth surfaces and are not suitable for transport on sidewalks, pavers and so on.
