I have found these straps to be an excellent value and very comfortable indeed. They come in 5 sizes (18-20-22-24-26mm) and have 2 floating keepers. They come in 23 colours in total, which is the most that I have seen anyone else selling.
Their length is 95mm on the buckle end (including the steel, screw-in buckle) and 135mm on the tail end and they do not taper. I have included many photos so you can get a better idea of what you are ordering. I will include a pair of good quality spring bars with each strap. Please note that the pattern of the camouflage models is always different. Also note that the bottom part of the camouflage models is plain colour.
Feel free to contact me for whatever questions you might have. P.S. If you require extra buckles for these straps, they are listed separately in my store, in silver or black satin steel (last photo here).
