All Peli Protector™ Cases except 1700, 1720 & 1750 come standard with our exclusive “Pick ‘N’ Pluck”™ foam: an easy, do-it-yourself system for custom-shaping the interior of the case according to your equipment. Layers of foam are pre-scored in tiny cubes. Simply measure your equipment, use tape or chalk to mark the foam, and pluck away.
