Many of the wristbands and bracelets sold on LP use snaps as the primary fastener. It is important to understand a few things about this type of wristband configuration. First, they are not always going to fit with pinpoint accuracy, there may be some wiggle room. For absolute perfect snugness, consider getting a wristband that uses a buckle(s) instead of snaps. But also, make sure you measure accurately, I try to get as close as I can, and knowing your true measurements makes that easier.
Which it brings us to my second point: If you're a repeat customer from years past, it's almost a certainty that any new wristbands you purchase will not fit exactly the same as your original did/does, even if it's the same exact item. Again, this is not an exact science, hides vary in weight and snaps may be positioned slightly different from your other cuffs.
