Trace out the item you want in the case and simply pluck the foam out by hand, no tool required. You can customize your case in less than 15 minutes.

The Pelican™ 1550 case is unbreakable, watertight, airtight, dustproof, chemical resistant and corrosion proof just like all Pelican™ Cases. It is made of Ultra High Impact structural copolymer that makes it extremely strong and durable. Its exclusive 1/4" (6.4 mm) neoprene o-ring and ABS latches seal perfectly and includes an automatic purge valve for quick equalization after changes in atmospheric pressure. Your equipment can fit into the high-density foam for total subjection and protection against impact, vibration or shock.
