5A Acrylic Drum Stick Red & Blue Glow Alternately Noctilucent Glow in The Dark Stage Performance

Show Original Everything is safe and sound! After the impact, they blink for 13 seconds, then they fade out, again the blow, they blink again. Includes 4 designs with batteries and LEDs! Batteries are not covered with a protective film. When opening the package, a couple of structures blinked. I wonder if they blinked on the way and how long the batteries last? When inserting a structure into a niche, unscrewing the cover of the Sticks - upon impact, the Sticks blink alternately in red and blue. Thanks seller. The packaging is not damaged. There are no scratches, this is important, because it is a gift! Let's see how long it lasts!
