The E-Crate is a 'green' alternative to corrugated boxes. E-Crates are stackable, durable, re-useable, space-saving, and cost efficient! E-Crates are a great alternative to office totes and legal boxes and offer a stress-free move for corporate relocations! E-Crates come in a slightly smaller blue size as well. You can also buy an E-Dolly to make moving even easier!
