Rubber nipple/cone for under key. This is a used to replace a torn or missing cone. You can use a small dab of super glue to hold in place. Please let me know when ordering which key this will be replacing as the sizes of the outer area around the cone are different for certain keys as shown in pictures above.

If you need the actual keys, this is a link to them:
