Storage Upgrade IV

The Storage Upgrade (IV) is an item added by Storage Drawers. It increases the maximum storage of a Drawer by 16 times its base value. For instance, with only one installed it will increase the maximum storage to 512 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.
