This is a safety mark for mothers and babies, with a suction cup type! I used to stick it directly on the car window every time I went out! From a layman's perspective, there is no noticeable major sun damage or dirt, but there are many small scratches, so we appreciate your understanding before purchasing! Size: Circle diameter approx. 12cm Instant purchase OK! Thank you! #MaternityMark #BabyOnBoard #MomAndBabyOnBoard #PregnantWoman
