Sky Impression Trays are made of a strong, rigid material that 
aids in the generation of consistent, distortion-free impressions.  
Compatible with a wide range of impression materials, Sky impression 
trays offer a system of holes and perforations to optimize flow and 
retention of materials.  The disposable, preshaped trays can be easily 
trimmed or flame softened to adjust for a custom fit.  Non-slip grips 
offer easy, clean removal.
