This is the  ORIGINAL NOGGIN TOPPER.  All NOGGIN TOPPERS are made double thickness from 100% acrylic, making them machine washable and dryable.  They are a one size fits most size.    My children ages 4, 10 and 15 wear them as well as many adults.  Please choose up to 4 colors to suit your taste.  As you can see, the possibilities are endless!  Additional colors may be added for an additional charge per color.
