The 3I-0907-MC3 holds three mics in a very compact case and is part of the 3I Waterproof Series of cases. 3I Series injection molded waterproof cases are constructed of ultra high-strength polypropylene copolymer resin and feature a gasketed, waterproof and airtight, submersible design (IP67) that is resistant to corrosion and impact damage. Its continuous molded-in hinge, patented "trigger release" latch system, comfortable, snap-down rubber over-molded cushion grip handle, secure stacking, and automatic ambient pressure equalization valve (MIL-STD-648C) all contribute to its military grade design. The interior foam is cut on the new water jet machine SKB is now using to cut custom foam and design new products. The case has convoluted foam in the lid for a compression fit. The 3i-0907-MC3 is allows for 3 mics to store horizontally. The 3I-0907-MC3 case measures 9" x 7" x 4" deep and is the most compact 3-mic case on the market and is covered by SKB's "MIllion Mile" Lifetime Guaranty.
