I just received it from Oura as an exchange for my previous one, but have another tracking device which works better for me. therefore this one is new and never worn.

Possibility to try the sizing kit to confirm size before purchase, just send me a message! Pick-up in person near Bahnhof Oerlikon or can be sent by swiss post within Switzerland.
