Is Shine&File Combo a nano glass nail file?
The correct answer is ‘no’, but this is also true of all similar products available on the market.
A nanotextured surface is a surface that is covered with nano-sized structures; these structures have one dimension on the nanoscale, i.e. between 0.1 and 100 nm (for more details, refer to https://en.wikipedia.org/wiki/Nanotextured_surface).
There are many similar products on the market that are referred to as ‘nano glass nail shiner’ or ‘nano glass nail file’. However, none of these products are real ‘nano’ products. The term ‘nano’ is used purely for marketing reasons. The polishing surfaces of these glass nail shiners and buffers are produced by a technology used for production of semi-conductors and the resulting structures have micro dimensions (not nano dimensions).
