Check The Back Seat For Me livestock ear tag reminding anyone caring for children to check the back seat for children. Simply place this tag in the child's car seat or booster seat and when you buckle the child remove the tag from the seat and use the stretchy spiral arm band to place the tag on your arm reminding you when you arrive at your destination to check the back seat for the child. Or hang these from your rear view mirror. These are double sided and include the stretchy spiral arm band. These are great for all parents, grandparents, and care givers.
