TOTS mask sizing question

Hello. Question about Trick or treats studios masks sizing. I currently have the 78/The shape by them. Fits nice, wouldn’t want it much smaller. I have a large head. I’m wanting to but the H4 and H5, as well as the H2 hospital Myers mask, but curious about how they fit. Do they run small or large? How are they relative to the shape mask?

Can’t speak for the 4 & 5, but I had an H2 (lost in a move) and it fit pretty similarly to the 78. I, too, have a large head - I can’t fit into the H18 at all.

I have a year 1 run of the H4 mask, which is small. I could barely fit it on my head, and I have a smaller head.

Can’t speak for the H5.
