How does it work? Very well! We are not sure, but what we do no is kids will love these and expected to sell out FAST… Very LTD stock at only 25p each. Unravel the foil light saber style stick press the bottom firmly and watch in amazement as the item starts to self inflate. Wait a few minutes until the foil saber wand has fully inflated give it a shake then let the duel between friends begin! (approx 70cm in length) a great party trick to WOW everyone. Great for lucky dip or pocket money toys alongside small prize every time wins. Comes in mixed colours 60/pc display carton.
