Retainer (orthodontic retainer) cleaning tablets Effectively removes plaque and stains. 36 tablets per box, 3 boxes total. Although unopened, I will remove them from the boxes and ship only the contents. I have stored them very carefully, almost without touching them, in a room I only enter after bathing, as I have severe mysophobia. However, since they have been handled by a person, please refrain from purchasing if you are concerned. - Product Name: Retainer Brite Cleaning Tablets - Contents: 36 tablets - Purpose: Removal of plaque and stains - Instructions: Dissolve in water and use - Temperature Range: Use at 20°C to 40°C - Precautions: Use once a day - Ingredients: Contains disinfectant
