Mouthpiece Case - Colors: Green, Blue - Purpose: Mouthpiece case - Size: 8 x 7 x 3cm Both are the same size. I received these from the dentist when I had my mouthpiece made. I didn't use them much and they were left on a shelf, so I washed them before listing. Please purchase if you understand that these are used items. ☆Please see my profile! I am a non-smoker! #AnonymousShipping #MouthpieceCase #DentureCase
