No mess…no worries! Boveda--the Global Leader in 2-way humidity control--is pleased to introduce their new Starter Kit for small wooden instruments (violin, viola, ukulele, electric guitar and bass, mandolin, clarinet, oboe and more). Boveda's system automatically protects your instrument against warping, shrinking, cracks and other potential damage caused by lack of humidification or too much humidification. It does so seamlessly without refilling or wetting sponges, snakes or discs. Simply place a Boveda packet in saddlebag, place in the case and close your case. Boveda does the rest, keeping your instrument at a constant relative humidity between 40-50% while it's in its case (closed)...the ideal climate for your instrument. Just change the packet when they get hard...easy, simple, and effective.
