I was wondering if you could share items?

I keep coming across items, armor, weapons, and that, that my character on children of mana can't use. I assume they are for other characters, I was wondering, if I play with a friend on the game, is there a way to give items back and forth between eachother?
weapons, armor, accessories, gems?

Sharing items between differant characters on your own gamepack. No
I am unaware of being able to share or trade items at all, but items and gems are easy to come by wile doing missions or revisiting places you have been to already.
Most items you can find even weather you can equip it or not.
