These adorable balloons with feet will be a big hit at your next party. They come in sets of 6 and are self sealing. Helium (not included) is not necessary but will help with the 'walking' effect.
They blow up easily by inserting a straw through the valve slot and inflating with air or helium. Then simply remove the straw and gently press the slot to seal. You can deflate to reuse them by inserting a straw as before and gently pressing the balloon to release the air.
