I have struggled for nearly 3 years to figure out the best way to display my bath bombs in my shop. I didn't want paper or plastic. I needed something that could fit in to almost any pop up space I created. I finally discovered the combination of these lightweight bamboo trays and sand. They keep the bath bombs in place and prevent them from rolling around. They just also pop on the black or beige background! Choose between: 8.5" x 11" - holds approx. 12 large bath bombs 12" x 16" - holds approx. 24 large bath bombs
