Per-ring pricing

• 2-pack — $9.50 · $4.75/ring — one mount plus a spare
• 10-pack — $34.99 · $3.50/ring — desk, car, wall and more

Why these rings

• N52 — the strongest commercial neodymium grade; secure hold through a case
• Halbach array — a one-sided field focuses the magnetism on the working face for a stronger grip from a thinner ring
• ±0.05 mm tolerance — seats flat and true in the printed pocket
• Nickel-coated — corrosion resistant; bonds well with CA glue and epoxy

How to use

Print the stand → drop in the ring and secure with a few drops of CA glue or 2-part epoxy → snap on your iPhone or MagSafe case. Free STL stand designs are included and emailed after purchase.
