This is described as "glass" however, what type of "glass" this may be is hard to say. For starters, it is not like glass in any way. Seems like hard acrylic. Does not feel like glass, or sound like glass when you tap it with a nail, or even look like glass. I do like it, but should be advertised differently on the actual materials used.  

It was a bit bigger than expected. I measured before hand, however, the width is a tad bit wider. No big deal, as it is going in a large window any way.

I feel the price is a but steep for it not actually being glass as described but overall, it is a gift, and I hope the person I purchased this for, likes it. I hope that with it not being actual glass, I hope it doesn't fade from the sunlight. Only time will tell.
