I can't gift the snowdown icons

I just tried to gift the snowdown icons to my brother, but it is not working. Everytime I click on "Unlock", an error message saying **You are unable to send this gift for one of the following reasons: exchange.storeprocessor.error Please choose another item.** pops up. My brothers account is only level 27, do you have to be level 30 in order to recieve the icons? Because I tried gifting a level 30 friend, and there was no error message. I also have only used one charge of my icon gifts, so there should still be 3 remaining. Would be cool if someone could look into this.
