This is a comprehensive set of eye drop accessories that came as free gifts with products, including 4 eye drop pouches, 2 zip-lock bags (2 per pack), and 3 sets of small eye drop bags (4 per pack). The small vinyl bags tend to wear out quickly, but the eye drop pouches last a relatively long time. By using this set together, you should have eye drop carrying bags for quite a while. I myself always carry my eye drops in a carrying bag to protect them from UV rays. Nowadays, unlike in the past, eye drops don't always come with carrying bags. Please take this opportunity to purchase this set of various eye drop bags that can be used for a long time. These items were all included as free gifts with products, so please understand that they are sold as-is with no returns or claims.
