I am pleased with the product, but I expected a larger quantity .......... very small container about the size of a US Nickle, if used sparingly you can get 2-3 whole long nails out of this amount. So if you expect to do more you will require to have a few more in your supply.

Definitely a waste of money, two out of the three that we put on our phones have already lost stickiness/keep coming off the phone, and one completely just broke after a day of use.

Ex Input:
The only reason this review is not a 5 out of 5 is due to the product color. In the picture the product looks to be a DARK brown, however the real product is a very neutral brown. The structure of the product is exactly what I was looking for and great for the price point, just wish it was as dark as the picture.
