I somehow managed to lose a couple of my 1-inch spring collars over the years, so this four-pack was an easy and inexpensive replacement. ✔️ Strong grip on the bar ✔️ Includes four collars ✔️ Easy to install and remove ✔️ Fits standard 1-inch bars ✔️ Great value These fit my standard 1-inch dumbbell handles perfectly and hold the weights just as securely as the originals they replaced. Once they're on, they don't slide around during workouts. The only noticeable difference compared to my old spring clips is the handle design. My original collars had three loops of metal, while these use two. It's a cosmetic and ergonomic difference more than anything, the grip is just as tight. Overall, they do exactly what I needed them to do. If you've misplaced a few spring collars or just want some spares for your home gym, this four-pack is a solid value and performs just as well as the ones that originally came with my equipment. See my pictures for the new ones (these), and my older three layered spiraled collars.

Not sure why but they were advertised as 25mm but were way bigger than 25mm. Measured at 30mm. Absolutely useless for a 25mm dumbbell. Buyer beware!
