This topper works well for both boys and girls and complements modern black, white, and metallic themes. It’s best for cakes that need a lightweight, sturdy accent without overpowering the design.

- Theme and style: Do you want elegant black and gold, humorous text, or vintage vibes? Align the topper or decorations with your cake and party theme.
