Just received a new card as unfortunately mine snapped in half.
The Quality was absolutely horrendous. I opened the envelope, white paint was smudged into the card and was flaking off. My hands were covered in tiny pieces of white paint just from handling it and the white paint is already starting to peel off the numbers already. It arrived literally 5 mins ago.
I honestly think Monzo needs to change supplier as clearly whatever quality assurance Monzo has put in place is not working.
