This carb cap top reminds me of the game pieces from a childhood board game called SORRY! ...but I won't apologize. They do feel oddly nostalgic in hand tho, sorry, NOT SORRY! ;P The marble on the top is a 4-pointed star, and the plus on the bottom has 3 matching spiraling strars. The plug on the bottom is 9mm long, and the diameter measures 11mm diameter.
