This pack was created for my daughters 4th birthday party. It is an 11 pc. pack. Includes shells, grass, coral, starfish, a happy birthday sign, mermaid and tails. We used them in various ways for the party. Necklaces, balloon weights, cake toppers and random yard decorations. Holes are not included in model but can be easily drilled or melted through. Coral limbs can be manipulated while hot for added variation. Models can double as accessories for aquariums. Use safe material with a 100% infill for water use. A Flexy Starfish pack used as guest gifts is available separately on site that compliments the birthday pack theme.
