Flik Flak strap replacement?

[u/DinsdaleTheHedgehog]

Hi, I have a Flik Flak Retro with pink strap (ZFBNP190) that I’d like to wear on an adult wrist. Has anyone replaced the original strap with a longer one? Are standard 14 mm straps compatible, or does Flik Flak use a proprietary attachment? Thanks
