Plugs are used to plug the end of the limbs, or to plug the head.
You glue the plug in, and it keeps your stuffing secure.
Also, it makes the vinyl "firmer" right where the tie strap (cable tie) attaches, which allows you to cinch the tie up tighter if you wish to.
You are purchasing a pair of same size rings,
please select your size from the drop down menu.
The size of the plug is measured across the diameter,
you just need to measure the diameter of the limb or head you need to plug and select the correct size.
Any questions, please ask before buying.
