Stretto humidifier for violin and viola case. The set contains plastic box and two bags.

Stretto  bag is immersed in water for five minutes. During the next two weeks it keeps the case interior optimally humidified. When the pad is nearly dry, the process is simply repeated. Due to its small dimensions (95 x 65 x 15 mm), Stretto can be mounted in any case. In this way, it keeps the optimal humidity of the instrument, gut strings and bow hairs. Easy to install in an instrument case.

Extremely easy to use, extremely useful.
