To place an order for your new custom mask, please enter the grade level of your student.  Mask sizes are determined by the age of the student.   I have all sizes and if parents or other adults are wanting masks we can order those as well.  Adult sizes come in SM, M, and L and can be found at the bottom of the page. This takes all the guess work out and I hope to make this an easy and worry free buying experience.  We strive to please our customers at Black Diamond Apparel. August 4, and there is a 10 day production period.
