Baby in Car Stickers:Package includes 2 packs of baby signs and 4 reusable suction cups. Baby on board stickers are inches. The combination of bright colors and prominent graphics lets other drivers notice the alert at a glance, reducing horn noise, no collisions, just a smooth ride. [ Bright colors] Bright colors provide extra safety for children in low light or at night. The baby warning sign can be used with any car style or color. Reusable:We use good PP material to ensure the safety warning sticker will stay with you for a long time. Baby car signs will not fade or warp in the sun. And because they are glued with suction cups, these panels can be reused. To reattach, simply boil in hot water for 5 minutes, wipe clean, and reattach. No marks] No glue required, so these safety warning stickers won't leave sticky smudges or marks on the glass. Simply allow the car surface to clean and dry before applying the reflective sticker. Just peel it off without leaving any residue on the car window. [Wide Application] The traffic signs can be used not only on various vehicles carrying children and young children, but also on vehicles undergoing driver training to reduce annoying tailgating and honking.
