I buy the glow necklaces that they have at The Dollar Tree here anytime I find them. Each pack has 2 probably 24" long, 1/4" diameter necklaces and they usually have several different colors........and they cost a buck. They aren't nearly as bright as the regular light sticks but the pink and green colored ones are decently bright and usually last for 3 or 4 days. I've used these things for just about anything you can imagine, they're cheap, they last and they've got a few different colors. Keep an eye out at your local dollar stores around Halloween and snag a few packs.
