"ABOUT TO POP!" POPCORN BABY SHOWER FAVOR BOXES look exactly like the movie theater ones, except these announce the condition of the expectant mother. These red-and-white-striped movie theater heavyweight paper boxes arrive at your door ready to fill with treats for your baby shower guests, so they can take them home and re-use them again and again. Many people fill these adorable containers with popcorn kernels for their baby shower party guests to pop up when they are at home. Both sides of the popcorn box have the red silhouette of a mom-to-be with the words About to POP! On her belly, and accented on the top with a sheer red, organza bow and popcorn-shaped “For You” tag.
