Here at GlowCity, we decided to only sell premium glow sticks. We didn't want to confuse you with an endless variety of different types, styles, and quality of glow sticks. We just wanted to make this a simple and easy way to shop for the best glow sticks! These are classic non-toxic chemical glow sticks. All you have to do is bend them until they crack, shake them up good, and they will remain glowing all night! These are perfect to add to your party, night activities, and other special events. Shop our selection of glow sticks and be sure to check out our other glow in the dark party supplies! Contact us with any questions you may have. We are happy to help.
