This is a new Baton padlock with two keys and the key tag (in case you want extra keys).  The body is made of brass and the shackle is made of hardened steel.  It is 45 mm wide.  The lock is similar to an Abloy.  Each padlock is keyed differently.  The keys may have some tarnish on them but this does not in any way affect their functionality.  The shipping will be the same regardless of how many padlocks you buy.  Please look at my other items on eBay because I'll combine shipping to save you money whenever possible if all purchases are made within one hour.
