Better Storage Mod 1.6.4

This mod adds more storage options, like Reinforced Chests and Storage Crates, as well as locks and keys for its
Reinforced Chests work just like normal chests. Compared to them, they have 12 more slots of storage and are completely resistant to creeper explosions. They can be made from different materials, like iron, gold, diamond, emerald, and if you use mods, copper, tin, zinc and silver. The material doesn’t affect the chest in any way other than how it looks.
