These arm bands are used for several reasons, main use is to prevent self injury of the face. I have made several pairs and have been asked by others i.e School teachers, and Paremts to make them for their children they come in assorted colors/prints. They are very similar to the Brand Pedi-Wrap (Pediatric Arm Immobilizers)they are a well known provider of these bands but I was approached by a mother (who's daughter has Rett Syndrome) her concern was that the bands were not made small enough for her daughters arm they would slide off, & they did not have Specific color choices i.e Solid colors and that they were too thick meaning the batting inside the band made them to thick I have found the thicker the band is you have a hard time getting them tight enough. These Arm Bands offer more of a custom fit at a Cheaper price I charge $25.00 a set 
If you want a Matching bib the cost is $30.00
These are very close to the Brand name Pedi-Wrap
