HP Invent 8 1/2 x 11 Photo Paper. And Storage Bag

This item is not in its original box so I’m not positive about all item specifics. It is an official HP storage bag ( zip top) and inside is photo paper. I’m not sure but I believe it’s glossy. I originally thought there were probably 100 sheets but I’m not sure about that. So let’s safely say there are 50+ sheets included. It’s been sealed up. Not sure of the age.
