Could someone please assist me in indentifying these two Earth 2x2x2 puzzles.
Earth 2x2x2s.png [ 346.41 KiB | Viewed 928 times ]
The black Earth (Left) has better turning than the blue Earth (Right) and is about 1/3 of the size bigger. Both bare the name 'K-Ball', however I am unsure as to weather that is the brand or name of the puzzle. I would love for somone to give me a date as to when they were produced and what brand they are.
Thank you in advance
