Set of 4 This is a clip-on type, not a tape type, so you don't have to worry about the adhesive weakening and becoming unusable like tape types. You can use it for a long time! I used these lids with different patterns when my daughter was in diapers, and they were very convenient (*^_^*) Compatible with all brands of baby wipes and mouth wipes! Please refrain from price negotiations m(_ _)m Thank you for your consideration. #★Ebisu★Brand New
