From the ManufacturerAnatomy of a Pelican Micro Case Ultimate Equipment ProtectionFor over 30 years Pelican has built a reputation for manufacturing the toughest cases in the world. As a matter of fact, we invented the category. Over these years we've seen our cases used for some fairly crazy activities...and important ones too.Pelican Micro Cases are created for your smaller items. Micro Cases look and function in the same way as the larger Pelican Cases, but are designed to protect your cell phone, iPod, camera, and other small items. Many of the cases are water resistant and crushproof, or impact resistant to provide maximum protection for your valuables. These cases will get your gear from point A to point B in the condition it's meant to be in: intact and functional. Stronger by DesignPelican Cases are made with a proprietary combination of homo and co-polymers, using an open cell core and solid wall construction, which is stronger and lighter than a solid core wall. Stainless steel pins are used in hinges and handles. WatertightThe secret is the tongue and groove fit with a polymer O-ring acting as a waterproof seal. Some models come with the Automatic Pressure Equalization Valve which balances interior pressure, keeping water out while making the case easy to open. Liner for Extra ProtectionYour valuables should be protected on the inside as well as the outside. Pelican Micro Cases contain a shock absorbent liner to minimize damage to contents in tough situations.
