I have misplaced the ring from my cap

Is the sealing ring from the cap of your Dopper missing? Please contact us through the contact form below. We will respond within a few days.

Please make sure to also enter your address details and send a picture of the cap in our contact form so we can send you a new sealing ring (free of charge).                              

Note: The ring is blue, making it difficult to detect in the blue cap.
