Mad Monster Question

[Type3Toys]

Can anyone tell me for sure how the Type 2 Monsters were packaged?
Was it card, window, solid or a combination?

The type 2 mad monsters came on card depicted the artwork of all for monsters in the front ,the same pics from the box's but small ,the back was blank just a white blank ,the cards in front were yellow ,I think for all 4, I have all four figures loose still that I got in 1980 at toys r us
