Sonnet keyboard kits are shipped in a carrying case included by default. Additional Sonnet top and bottom cases do not come with their own carrying cases.

There are two versions of the form-fitted carrying cases for the Sonnet 75% keyboard. Both feature Mode-branded zippers, a velvet-lined molded interior, padded carrying handle and an elastic storage pocket within the top shell for storing Plates, PCBs, foam and other extras.

The fabric variant features a Nylon covering, slightly expanded top shell storage depth and a padded four-pocket divider for extra storage of smaller parts bags.  This variant also fits the Mode x ModMusings Encore keyboard. 

The polyurethane variant features a slimmer overall construction and a faux-leather textured polyurethane outer with a supple feel.
