84/85 Topps Hockey - Michigan Test Packs?
 

This video https://www.youtube.com/watch?v=FjS3kGsjTOU popped up in my feed.

The pack reminds me of the '83 Topps Baseball Michigan test packs. However, I had never previously encountered a similar pack wrapper for mid-80s hockey.

Does anyone have any info on these?

This is the correct wrapper for this issue. I opened many of them! I have a 3200 count plus is singles and about 25 each of Steve Yzerman and Wayne Gretzky.
