Guild Wars 2

If i have 10 pieces of leather or 10 potions how do i give one to a friend or party member without having to send all 10? i haven’t been able to figure this out.

There are numerous threads on this, but you do so by holding alt, then trying to drag the stack. It will bring up a box where you can then type in the # you want to seperate from that stack. Then you can mail that new sized stack to a friend/party member.
