CIY, cut your own foam! Foam sheets are 8.5x11 in size and include adhesive on both sides. Acetate sheets are 8.5x11. Package includes 4 sheets of foam and 4 sheets of acetate. Use dies to cut your own shakers from these foam sheets. Please note: You must layer 2 cut pieces together to make the shape thick enough to hold toppings. Acetate will need to be hand cut to cover your foam shape. Foam sheets may have wrinkles throughout, this is part of the manufacturing process and will not affect performance.
