The top piece of glass is

This screen protector pack does not come with a hard piece of plastic for applying the screen protectors evenly.

The bottom protective piece did NOT cover the entire touch screen, and the top glass leaves 7 large bubbles that I could not get rid off

The top glass was perfect and went on fine but the bottom piece that was to go on my new 3DS XL acted like a different material and didn't apply well at all

The top glass piece is not uniform in size and has a bubble in the top and lower left screen

Gave it 4 stars because its not a perfect fit, both top and bottom pieces are slightly smaller than the displays itself.

Let me start by saying I absolutely LOVE the top screen piece

The top piece is tempered glass while the bottom piece is a plastic film
