How long we can keep items in Mailbox?

Question

Is there any time limit after which items disappear from Mailbox? I would like to invest in huge amount of ultimate mana potion and keep them in Mailbox (as we know price for supplies has been increased once, so that may happen again in future).

Answer 1

There are no limit of time in mailbox. I found last time my parcels from 2017. But remember..flower pots        need water  or they will die   if you forget about them.
