Storage Upgrade I

The Storage Upgrade (I) is an item added by Storage Drawers. It increases the maximum storage of a Drawer by 2 times its base value. For instance, with only one it will increase the maximum storage to 64 stacks from 32. It can be applied by right-clicking with it on a Drawer or placed manually in the Drawer's GUI when right-clicked with an empty hand. The Upgrade can be removed through the Drawer's GUI. Upgrades stack additively with each other.
