Simply Submerge: Submerge the hatching unicorn egg toys completely in room-temperature water; within 12-24 hours, the shells will crack, and the unicorn will begin to hatch. If the water level is low, add more water to ensure the eggs remain fully submerged.

You can play with them yourself or send them to your friends, nephews, nieces, and more. Each egg measures approximately 6 x 4.5 cm/2.36 x 1.77 inches. Learn Patience: Easter water growing egg toys typically take about 12 hours to grow in room-temperature water.

Individually Wrapped: Since the water-growing toy is individually wrapped, you can use each egg according to your needs or preferences. Furthermore, the individual packaging allows for easy sharing with others.
