Due to an error in production process, our beloved official TENETO Loyalty Mugs may need to be replaced in some cases. If your TENETO Loyalty Mug contains a personal number like T-XXXXXX and not TC-XXXXXXX, you may have this mug replaced by us. The faulty ones contain an error in second half of calendar year. If you are not using a calendar, you are perfectly safe using the mug you have.

In case, you would like to have the faulty mug replaced, please contact us at This e-mail address is being protected from spambots. You need JavaScript enabled to view it stating your personal number from the mug, together with full contact details, including email and phone number and address we can send the good one to.

We are sorry for inconvenience.
