My eyes instantly locked onto Diesel's new "Lock In" wristlet on my last trip to Macy's. The closure on the purse is the huge, metal twist lock in the center. The metal on the lock makes the purse quite heavy which is actually sort of a good thing... it's almost impossible to lose if you're feeling the weight of this bag. It comes in about 4 different colors but looks best in black or ivory in my opinion. Perfect bag for heading to the club... if you're into that.
