I bought my Dianese Full Metal glove from these guys, the quality of service and the communication received was above excellent.
I remembered the shipping was somewhere around US$25-$30, they only ship on fridays but I received my gloves on the following wednesday.
You place an order with the item number/colour number and the size, and they will email you back asking you for fit and a shipping quote.
You pick the shipping method and they will ship the goods on that friday.
