By the concept of using a built-in pump to create a vacuum, an absolute anti-moisture environment is ensured to store a precious violin. The top cover is secured by Polycarbonate (PC) to assure higher transparency and rigidity. With the built-in electronic meter's surveillance, internal humidity, temperature, and pressure are shown through an LED and LCD signal screen and can easily be read by users. The VAM Violin Dry Box combines elegance with modern scientific and electronic design. The X-band reinforces the structure rigidity, provides visual balance and aesthetics for the box. The elastic webbed bands reinforce the body structure, and can be used as straps. Dual protection is provided by Boyle's Law: when the air is pumped out, the internal TPU air layer will be bulged to wrap up the violin.
