Guild Wars 2

I have one (maybe silly) little questionon this:

Gaile Gray.6029:

For instance, if you purchased three Molten Mining Picks to be used by three different characters, you should convert one of those picks to an account-bound item for use by any character on your account. Upon deletion of the second and third Molten Mining Pick, we will issue a gem refund for the additional Molten Mining Picks you no longer require.

I bought 2 bone picks. One is now converted to account-bound. The second, character-bound one, lies in the characters inventory. Do I have to delete this one myself, before applying for a gem refund, or should I keep it in the inventory as proof, that I do have two picks of the same kind?

thanks,
Z.

I mean the chest-armor. Can’t remember, where I bought it for my ranger, and I want the same for my enginieer.

thanks,
