The Snow flake is the one sold by Holiday Coro. The Merry Christmas letters are coro with 200 incan lights in each letter. I went to a sign shop and cleaned out all of their scrap and misprint signs, this was the 4th year in service. My plans this year include making the Merry Christmas RGB in the same type of construction as the coro flake.
I added a picture of one of my letters. I only painted the front but probably should have gotten new paint, the old miss print bleed through.
