From the folks who brought us the hardcover book "Goodnight St. Louis" as well as the companion coloring book of the same name comes a fun new micro-puzzle! It is 150 tiny pieces that make a 4"x6" puzzle when completed, which you can disassemble and store back in its nifty little test tube, or you can frame and hang as a cute little piece of STL art. Either way, you'll have a blast with this fun puzzle, and you can't spell "have a bLaST" without STL!
 
Contains small parts, recommended for ages 3+.
