50 Green-Colored Plastic Bottle Caps All caps have been cleaned with bleach, washed, and dried. I have checked for any dirt or imperfections. I do not have any pets or smoke, so there is no concern about odors. Material: Plastic Please refrain from purchasing if you are overly concerned about minor imperfections, as this is a personal sale. Thank you for your understanding. Thank you for viewing! m(_ _)m
