Ostax

Kirjeldus

The front part of the case is equipped with an automatic exhaust valve with a sealing ring. It is made of permeable non-woven fabric, which
can automatically adjust the pressure difference inside and outside the case while waterproof, making it easy to open and close the case
body. There is also a mute spring lock, which is easy to operate with one hand and can prevent the case from opening when it falls down.
