you CAN, however, put the mage-summoned toys in a player house, and they do not poof. So have the mage load up a bunch there, and then the alts can go grab it whenever they need it.
This works great for everything except the summoned jewelry (Nastel's, etc). For some reason, these are LORE, so you can only have on set in the house.
