Whether you are going out to a party or having a festive evening at home, these LED finger laser beams are a perfect addition to the occasion. The set comes with four pieces: red, blue, green, and white. The replaceable elastic strap fits most fingers. Each unit is powered by 3 button batteries (included in the package).
For almost the same price as a package of glowsticks, you can rock these over and over. Available on amazon.com.
