Everything is fine, I had to replace the original tip for my pen and yes it fits and enters easily. For one thing, they're not soft, but a bit hard and even a bit pointed. So if you are looking for soft rubber tips, take a look. I don't think Revain sells them anywhere but they still work as is and if you have a tempered glass screen protector that's fine as your screen is protected.
