To ensure a secure yet comfortable fit, measure around your wrist with a flexible measuring tape or a piece of string, then compare it to the chart below:

• Small: 7 inches
• Medium: 7.5 inches
• Large: 8 inches

Tip: If you’re in between sizes or prefer a looser fit, consider sizing up.

These elastic wristbands are designed to stretch slightly for comfort, while still remaining snug enough to be easily scannable with NFC devices.
