Which model will you get? With a wide range of available models in each "series," it's always fun opening blind bags. They're great for parties and gatherings, as gifts and as a fun activity. Put one at each place setting at the table, add them to goodie bags, or hand them out and make a game by offering a prize for each person who gets a particular one.
And to make it even more fun, each series contains one or more "Chase Pieces," that when found, can be worth quite a bit of money on eBay!
