Review on 💌 FLYOME Invisible Upgraded Message Goodies: Unleash Hidden Surprises! by Andrew Vogel

This product is designed for convenient use of a marker and flashlight. The concept is amazing. However, the 4 pack I received only really worked for 2 parking lights. I'm pretty sure it's a battery issue and I'll try to replace them, possibly depending on the cost of the batteries due to the price of the markers. That's why I only gave them 3 stars. Also, they write well and the light at the two workstations does the job.
