We just got a new shipment of these great 40mm cans in! The 40mm ammo can measures approx 17 1/2" Long x 10" High x 6" wide. Top comes off, latches on both sides. There is a handle on each end. Excellent condition, these are a great size, just large enough to hold a lot of tools or ammo without being so heavy when full that you can't move it!
