What makes Pine Ridge Archery kisser buttons so innovative? The “Slide On Kisser Button” does not have a slit in it like regular kissers, so you can slide it on the string (even over the loops at the end) for a secure fit that will not move. The secret behind the Pine Ridge Archery Slide On Kisser Button is the unique blend of materials that make up the kisser button. The material is soft while others are hard plastic. Hard plastic does not allow you to flex over the loop of the strings and travel down the string into position. With the Pine Ridge Archery softer, yet super-strong material, the kisser is flexible and more comfortable on the lip. We also have “Slotted Kisser Buttons” made of the same soft material, but they have the slit in the side allowing you to install the kisser without removing the string from the bow. This is great for the consumer or a time crunch in the shop. The Pine Ridge Archery Kisser Buttons also help eliminate bow string noise and squelch string vibration thanks to the soft, durable material they are molded from
