Magic Tricks

The description sure does say that about the sizes...they come in "Regular" (adult), "Junior" (child), and "Jumbo" (extra large) from Rocco's site directly.
Usually, if there isn't a dropdown to pick your desired size, you can request such in the comment section of the order. You may want to contact PM customer service to verify that the sizes are available.
As the title header states "...Prisma Lites PAIR..."
Yep, you get two.
But, you can also order as a single.
