Thank you for viewing! Please read my profile before considering a purchase! This is a set of 38 green-colored penlights (chemical lights). They glow for 8 hours and are 15cm long. Please refer to the third image for a sense of the length when held. The color and glow are both excellent! The color reference is at the end of the images. These are leftovers from a wedding dress color guessing game. Unused and brand new. Shipping is free. Thank you. #penlight #chemicallight #cyalume #wedding #dresscolorquiz
