Hey Chris,
Thanks for reaching out! For questions regarding your order, send us a message at theory11.com/support. We can check into this for you. Wristband orders are usually sent using First Class International, a ship method that takes 7-21 business days to arrive once shipped. If shipped on the 16th, this will likely take a couple weeks to arrive.
First Class International does not provide "live" tracking the entire time it is en route to you. Once the package leaves the USA (usually from Jamaica, NY, or New York, NY, our outgoing ports) tracking won't update again. This does not mean that your package is stuck or that anything is wrong. Your package is still en route to you and will continue to move from location to location even though tracking does not update.
Have a great week!
