Our Yellow 4" Glow Sticks can be used as party favors for birthday parties, Bar Mitzvahs, other special occasions, and for nighttime vending as well. Our yellow light sticks are great at concerts, carnivals, and dancing. Each yellow glow stick features a hole at the top that allows you to attach it to a lanyard (not included) for hands-free glow fun as the night goes on. Or, use your yellow glow sticks as part of your party decor, whether that means to light up your centerpieces, accenting floral arrangements. To activate your yellow light stick simply bend in the center until it snaps then shake to disperse the glow product. Our 4-inch Premium Yellow Glow Sticks are sold in increments of 50 and are bulk packaged in poly bags to ensure quality and freshness.
