This phone holster is designed to attach securely to your backpack's shoulder strap. 

A MagSafe wall mount is applied inside, allowing you to easily and quickly attach or detach your phone. The powerful MagSafe magnet ensures a strong hold—your phone won't fall out, even when you're jogging or jumping.

Attachment Options:

 25mm silicone band (similar to a helmet lamp strap)

 velcro band

Both options provide a secure and adjustable fit, so your phone is always accessible on the go.

The wall mount comes with 3M adhesive tape. If you ever need to adjust or re-apply the mount, you can use the re-apply support disk with double-sided tape to restore the adhesion, making the mount reusable.

To use this holster, you'll need a MagSafe-compatible smartphone or a MagSafe-supported case. I designed this model specifically for my POCO F7 Ultra with a MagSafe case, but I've also successfully tested it with a Pixel 7a with a MagSafe case.
