Some of the most beloved storage containers are totable. Our favorites include a cake box, a round sandwich holder, a soup mug, and a lunchbox.

THEY'RE SPECIALIZED: The cake box (pictured) has a handle and a base that flips over to become a serving tray. The sandwich container fits a roll and has a pop-out plastic cup for a condiment. The soup mug sports a vent cap for the microwave and stays hot long after you've nuked it. The lunchbox compartmentalizes the sandwich, chips, juice box, and dessert.

WHAT THEY COST: Round Cake Taker, $25; Round Sandwich Keeper, $12.50 for two; Rock 'N Serve Soup Mug, $12.50; Lunch'n Things container, $9.50: all from Tupperware, www.tupperware.com.
