Water Marbles - Dinosaurs & Mermaids

Just add water and watch the Water Marbles grow in size! Our Water Marbles come in a variety of colours and once grown, you can keep your Water Marbles in an airtight container for weeks or they can be re-hydrated once they are dehydrated!

Please note that this contains small parts and therefore, should be kept out of the reach of children under 4. The marbles present a choking hazard and should not be consumed. Please supervise use at all times.
