There are slippery-proof and collision-proof strips at the bottom preventing the body of the instrument from hitting the dry cabinet. The professional slippery-proof design keeps the stored instrument well in place. The exterior of the cabinet is made 0.9 mm strengthened steel boards. The special weight loading structure protects your instruments from strong shocks.

Music instruments are very sensitive to moisture; in a very humid environment, the wooden body of music instruments may absorb moisture and expand. Expanded back and the surface panels maylead to off tune. On the other hand, if the environment is too dry, the instrumentsbody will shrink, making the material brittle and that can lead to off tune as well as many other problems. Humidity control is especially important for guitars, violins, cellos and many wooden instruments; if the humidity drops too much, the wood may crack and deform, which are irreversible. Therefore, humidity control is critical and should be professional.It is necessary to have a stable humidity to protect the instruments from damages and to prolong the lifespan of the instruments. 
   Take guitar as an example here. The physical absorbent type of dry cabinets on the market has a fluctuating moisture level greater than ± 8%. That is, when you set the humidity to 50%RH, which is suitable for guitars, the RH may still drop to 40% or even less, and that is not a stable humidity-controlled storage environment for guitars. Actually, it is too dry and can actually damage the instrument. You won’t recognize the danger of unstable storage environment until you beloved guitar is ruined.
