A year or two ago the exact brand I used was discontinuing their product so it may be more difficult to find now. I do want to mention something I've noticed is that the adhesive on the page pebble is not very strong. You may want to experiment with a clear superglue or something that dries clear.
Also, unless you want it to only be temp, use a good double sided tape like 3M's red automotive exterior mounting tape... this stuff is near impossible to get off once it sets. Be sure to clean the surface with alcohol, especially if you use any dressings on your dash. I have a MOMO decal with the proper size/pixels I'll see if I can dig up and post for everyone.
