An excellent value for money, these come in 4 sizes (18-20-22-24mm) and have 2 smooth, floating keepers. The straps themselves are black and have a nice diamond pattern on both the top and and on their under side, so they wear quite comfortably as they do not stick to the wrist. Their length is 90mm on the buckle end (including the steel buckle) and 120mm on the tail end; so not short but not too long either. The straps come with 2 buckles; a black buckle mounted on and a second, extra steel buckle, so you have a choice for both steel and black cased watches.
A good quality pair of spring bars is included with each strap. Feel free to contact me for whatever questions you might have
