By laminating two layers of soft EVA together, the material has excellent tensile strength. All of these features make the Pro-form mouthguard laminate the material of choice for custom-made mouthguards. There are six different styles offered through the Glitter Guard line: Blue, Yellow, Purple, Pink, Orange and Green. The Glitter Guard Laminates come in packs of 6.
