Item number 2360038,
Our kantele carrying bag (which can be used for most any comparably-sized instrument) is made of heavyweight black nylon. It features a soft nylon interior (Cordura on one side of the inside, so your tuning pins won't poke through the padding), a generous exterior pocket, and it even comes with a shoulder strap.
This case measures 17.5" by 31", outside dimensions.
As an added bonus, our kantele bag even includes a Folkcraft Instruments logo, classily embroidered on the outside pocket.
