The merchant sends a key cap, hinge clip, and rubber key cup with each purchase. The cups I've received in the past are almost certainly used, because the edges arrive ripped. This isn't a huge issue though, they still work just fine. My frustrations with this business come from email interactions with customer support. On one occasion, the included hinge clip arrived broken, and the business refused to send a replacement clip. They said they would in emails, but never responded after that. Recently, I purchased another two keys, received a shipping confirmation, and then was informed that they were out of stock. I was given the option of only purchasing the hinge clips (exactly what I needed) but after a week, I still have not been shipped hinge clips. The business is trying to stall until their stocks are replenished so they can charge me full price for the repair kits. They don't even sell hinge clips ala carte on their website. Huge waste of time.
