The M40 Micro Case protects compact equipment such as phones and small tools in a waterproof, crushproof, and dustproof shell. Rated IP67, it can be submerged to about 3.3 feet for up to 30 minutes while a separate o-ring gasket seal maintains watertight protection. Dual latches and a padlock hole add security, and a removable no-slip bottom liner helps keep contents stable. An automatic pressure equalization valve balances interior pressure.
