The pins have about 8 mm height and 5mm diameter - the specified adhesive force seems quite realistic. Due to its small size it difficult to spot, cover and not much to see in the chrome look also good. I have these pins ordered to use them at a Metallpinwand. Stapled directly onto the metal, it occurs to me (man) heavily emphasize it again, so strong are the little ones! Actually, for their size (and in my use) almost too strong, my wife does not buy from these things! The next time you purchase I would definitely order slightly longer and perhaps thinner pins.
