These collars are made two full inches too short (and they shrink -- see below). The 10", which I bought, measure only 8 inches from the mid-buckle clasp to the furthest hole. I'm using these as ID tag straps for equipment and luggage, and I'm actually happy that they are much shorter than comparable pet collars. I can't find 8" pet collars anymore. They are also somewhat defective because the stitched end that wraps around the buckle is wrapped the opposite way most "normal" pet collars are done, with the raw side on the outside of the collar. Again, compared with the other pet collars I've purchased, the raw side is so rough that you wouldn't actually want it rubbing against your pet's neck. But it is less attractive this way, to be sure, though it won't affect the performance of the collar. UPDATE: I must really recommend NOT using these collars on pets -- they SHRINK for some reason, perhaps after getting wet, but I really am not sure. As mentioned above, I didn't intend to use these 10" collars as actual pet collars. As it turned out, though, a neighbor found an abandoned litter of kittens and convinced me to take two of them, and I very handily had this bunch of little collars in various colors. These 10 inch collars were a very roomy size for my scrawny 3 month old kittens. But when I checked on them a week later, I saw that the collar was kind of tight on one of them. I unbuckled it to move to a different hole, and noticed that it was very frayed, obviously from the cat scratching at it. I took it off to see if there was something else about it irritating the kitten, and saw that somehow the scratching had actually made the collar curve --- one edge of the collar had become shorter than the other. I checked the other kitten's collar, and it had the same thing, though less severe. I didn't think much of it, and found some other collars for the kittens from my stash, ones from another manufacturer that were the proper length for a 10" collar. Today, I took out my box of little collars, including the old frayed ones plus some new ones from this company, and instantly realized that not only were the old ones frayed and misshapen (curved), they had also become shorter, by a full inch on one of them! I am not aware of my kittens having ever gotten really wet, but it could have happened. I am at a loss to imagine anything else that could shrink a nylon collar -- BEWARE!!
