Why would you even want a pre designed tip? They look so cheap on the nail. Unless that's the look your wanting. If I was you I would design my own with polish after the product has been applied. That way it's not a permanent fixture and you are able to change the design as and when you want.
It's just something a friend had done at another salon and wanted to know if I could get some for her so she could have a better choice of designs to pick from. It's not something I want to use on myself or clients
