Query: Big hit for birthday presents - 2009

We received a kit as a gift and then I bought 2 more to give away as birthday gifts. The 6-10 year old set love this kit - easy to do, can do without supervision by mom, and then you can immediately use them. The only downside is that there is a risk that the flip flops will be too big/small for giftee.
