Dark Souls weapon repair

What is the item called that you can buy to repair weaopns and stuff at the bonfires?

I'm pretty sure it's called repairbox. 3000 souls at the vendor in Undead Burg.

Thought so, thanks. I was thinking it was a one time thing but at that price no way

Yeah that repair powder from the same vendor is one time use...500 souls I think.
