I made 12,, 6 in clear glass and 6 with a light blue tint. They were all 1" diameter. The inside black balls were different sizes respectively between the two shades. I went with this many and types to make it easier on them to choose what would be best for them. There was a 2 week window to get them made and have them on their door step as shooting was on a very tight schedule. Ill have to look around and see if I got any photos of them. I did have a terabyte burn up and lost all 1,000 gigs of photos so I may or may not be able to find the pix.
Not sure if it made the credits, Alan set up the contacts.
