For your safety, the Béa Applicators are single-use medical devices and cannot be reused. It would be very difficult to sterilise the Béa Applicator properly, and it currently isn't possible to reload a new cap into the applicator, so it wouldn't be effective. We are very conscious of our environmental impact and want to ensure our kits are as sustainable as possible. Rest assured, we are looking into options for making the Béa Applicator reusable in the future, but given that it is a single-use, regulated medical device, this will likely take us a while to achieve.
