This item has special properties you can adjust with the Wrench.
The Donation Box was released during the Home Pack update, but does not come with the Home Pack itself so do not buy a Home Pack if you want a Donation Box.
It functions like the Holiday Gift Box allowing other Growtopians to give a item gift (min rarity : 2) and say a few words like "Thats what you wanted!"
When someone donates something it will say in the chat "<name> has donated <amount of items donated> <items donated>"
Plus, its better to use a donation box than a display box as the growtopians give you items with min.2 rarity and people cannot see what you're giving.
