We discovered Wikki Stix when we were staying at a hotel in San Diego. They gave them out in the restaurant instead of crayons. My kids (3 and 5 at the time) thought they were WAY more cool than crayons and a coloring place mat.
What a simple idea! They are simply bits of colored string covered with a wax coating thick enough for them to bend and stay in position! Like a candle wick, hence the name I suppose. Kids can make all kinds of things with them.
We use them in restaurants, the car, my purse, anywhere that an instant emergency diversion might be needed. They also make great stocking-stuffers. Santa brought some this past Christmas. Available in primary and neon colors.
