Keys with orange turtle keychain

I found a set of keys this morning around 8:15am outside the Santa Maria Novella train station in Florence. The keyring has several metal keys and a bright orange silicone turtle keychain that really stands out. There’s also a small black USB drive attached and a frayed red thread tied around the ring. The keys look a bit worn but all functional. If these are yours, message me here with the orange turtle detail and the USB drive to verify, and we can meet up at a nearby café or at the station to swap.
