Hi,it can be stacked, and the inner and outer filter threads are the same.

Compared to Black Pro Mist I assume? So mica glass indicates the strength with 1, 3 and 5. Black Pro Mist is 1/8, 1/4, 1/2, 1, 2, 3. From my personal experience I would say Glimmer Glass 1 is somewhere between 1/8 and 1/4 strength. But closer to 1/4 when it comes to spread. I hope it helped :)

It is original fine. packaging and everything. Also had USA on mine if I remember correctly. They probably changed it on the production line while the photos will stay there forever.
