Each 400-part map-sterpiece is custom made for your ZIP code, down to the house number and street name (takes about 2 to 3 weeks for delivery). Based on U.S. Geological Survey maps, you can see everything there is to see in your neighborhood, or try a different ZIP code to find out how the other half lives. The product is made from high-quality 1.5 mm millboard, and the pieces fit together like butter. Jennifer Varon, the Firebox representative at Sandbox Strategies, tried one herself. "A bit of cheating went on, though, because the whole office helped. It took about four hours," she told TDmonthly. Both the customized aspect and the incredible detail resonated with the people who tested them out. "They show every street park and school within the designated ZIP code,” she added.
