I noticed some of the reviews said the size was inconsistent, or they were cracked, or the number was off, but I didn't encounter any problems. I wanted some that were made in the U.S.A. to avoid possible lead contamination, and these (mine anyway) were consistently sized, and none of them were cracked. I also appreciated that there was one extra marble of each color, so instead of the 10 per color that it mentions, I got 11. I wanted marbles that were clearly different from each other so I liked that they were solid colors. I like cat's eye marbles, but sometimes the colors are so similar you get them confused with someone else's ( I play with my grand daughters.) as you make your way across the board during the game. I would recommend these to anyone that needs replacement marbles for their board games, and I'm really glad they worked out.
