Review on 🚦 10pcs White Round Reflector with Center Mounting Hole and 10pcs #8x3/4'' (M4x20mm) 304 Stainless Steel Screw for Road Safety, Mailboxes, Tunnels, Cars - D-020-W by Suhas Payton

These reflectors are as advertised. Can be used with self-adhesive backing and/or screwed. I used them to level my RV's parking lot, which made it easy for me to get back up using just the mirrors. White in a good clean area. Red right at the edge of the parking lot. I now have many add-ons to use as needed.
