The UltraBox has been engineered to take protective cases into a new field. The UltraBox collection is made of UKtekmat 1.0 material - UK's proprietary non-corroding engineering-grade ABS plastic blend, making them as indestructible and durable as its larger counterparts as well as incredibly lightweight.
The UltraBox line features two style configurations: clear lid with solid base and solid lid with a solid base, and be available in 7 different sizes. The series also has the UK proprietary mechanical pressure relief valve which insures easy opening after altitude or temperature change. With its o-ring seal, the UltraBox is waterproof, airproof, and moisture-proof—providing the ultimate in lightweight protection.
