Rainbow Gradient Number 1 Foil Balloon forms a tall numeral one in the same pastel blend of pink, yellow, and pale blue that runs the length of the shape.

Why this piece: its slim silhouette takes up less display space than wider digits while still standing out; the gradient finish coordinates with the rest of the rainbow number set for multi-digit ages; the balloon inflates through a simple valve without special equipment.

Includes one number-1 foil balloon with a self-sealing valve, inflating to approximately 40 cm (16 inches). Dimensions: 32 in.

A standard balloon pump fills it with air for tabletop or wall display, or it can be inflated with helium through the same valve for a floating numeral - both options need no extra tools.

Fits first birthdays, 21st celebrations, or any occasion built around the number one.
