Review on Meite 2 Inch Stainless Staples Similar by David Lambert

bought this for some boat upholstery, when i open the box there is a note 'for internal use only' in the hidden box but nowhere in the description does it say that .not even outside the box. This is the first time I've seen stainless steel braces for internal use only. I could buy the galvanized one for half price if I want it for interior use.
