Twinsert pharmaceutical leaflets, also known as Twin-Serts or Twin-Leaflets, are a type of folded leaflet commonly used in the pharmaceutical industry. These leaflets are designed to provide detailed information about a medication or medical device to patients and healthcare providers.

Twinsert leaflets are called “twin” leaflets because they combine two separate leaflets into one package. This allows for the inclusion of more information in a smaller package size, which is beneficial for pharmaceutical companies looking to reduce packaging costs and environmental impact.
