What to Compare Before Buying
- Badge size: The holder is stated to fit badges or access cards up to 4.75 in x 2.75 in (12 cm x 7 cm). Check your card or badge size against that space.
- Arm fit: The band length is stated as 12 in to 18 in (30.5 cm to 46 cm). Compare that range with the arm size and any clothing you expect to wear with it.
- Contents: This is an arm band holder with a storage pocket, so check whether you need only badge carry or space for a few small items too.
Compatibility, Size and Fit
The main fit checks are the badge opening and the arm band length. The badge window is sized for IDs or access cards up to 4.75 in x 2.75 in (12 cm x 7 cm), and the band length is stated as 12 in to 18 in (30.5 cm to 46 cm). If you plan to wear it over bulkier clothing or a jacket, check the fit range against that setup before choosing an offer.
Before You Decide
Confirm that your badge or card fits within the stated 4.75 in x 2.75 in (12 cm x 7 cm) window. Check the arm band length against how you plan to wear it, especially if clothing layers are involved. If you need a simple arm-worn holder with a secured pocket and visible badge window, this format matches that need.
