These bee molds are just too cute! Epoxy cast, they are aproximately 3.5"x2.25x1". There is a twist to customizing this product, you can either pick your colors as you do with any other product OR you can choose the "realistic" option and color your bee, flower, and comb what ever color you want. Want a purple bumble bee? You got it! I'll be sure to mix the colors of each seperately and allow them to set before adding the rest of the epoxy. If you select a regular bee, simply select none on the realistic selections.
