The tags need a slot or a way to slip onto a collar with ends that cannot be removed.

We have the style you need for an adjustable length collar, but you ordered the slide-on style. If you go back to the page you ordered on you will see a picture of the closed ended style and on the page we call out the fact the style cannot be installed on an adjustable length collar and offer a link to the correct page to order the adjustable style on. We do all we can to prevent customers from ordering the wrong style CollarTag™ for the kind of collar their pet wears.
