I opted to change my initial spruce Disco to the monogrammed card also. I absolutely love the look of it with the initials and subtle pinstriping. Showed my wife last night and she was like “what’s that black card??” I told her and showed her all the optional card faces on the site and she’s now decided to replace her purple card with the monogrammed one as well. It looks really classy and high-end compared to some of the monochrome cards.
It’s selectable from inside your online account. It says that you can switch it up every 30 days (they’ll mail you new cards). As a side note also, my spruce card is still valid and active. I keep it in my safe in case my monogrammed card ever gets damaged or lost - I can deactivate it in my app and grab the spruce card, put it in my wallet, and continue on.
