No Sew 12-piece metal ring set 6 colours .5 mm 46 mm 56 mm cell phone battery

Universal metal rings for MagSafe charging

This 12-piece set supplies ultra-thin metal rings that adhere to a phone or case so it can work with MagSafe-compatible wireless chargers and magnetic mounts. Each ring measures .5 mm thick with a 46 mm inner diameter and 56 mm outer diameter. Six colours — silver, black, white, blue, pink and green — let you match or contrast your device. The rings are non-magnetic themselves; they simply provide a ferrous target for magnetic holders.

Limits of the MagSafe magnetic interface

The rings only function when paired with a charger or mount that uses Apple’s MagSafe magnetic array or an equivalent 56 mm diameter magnet pattern. They add no charging capability on their own and will not align with Qi chargers that lack the specific magnetic ring. Thickness is minimal, but the adhesive requires a smooth, flat, non-textured surface; curved, leather or heavily textured cases may prevent a secure bond. A protective film covers each ring and must be removed before use.

Simple peel-and-stick installation

Clean and dry the outer case surface, peel the protective film from the ring, then press the ring firmly into the centre of the MagSafe zone. Misalignment is the most common issue — if the ring sits off-centre, the phone will not lock to the charger or mount reliably. Once applied, the adhesive is strong; repositioning usually weakens the bond, so verify placement before final pressure. Users who frequently swap cases will need a new ring for each case.
