Yes. Ray's case is made of stainless steel, which contains nickel. Do not use Ray if you have a nickel allergy.
Is Ray nickel-free?
No. The stainless-steel case contains nickel, so Ray is not a nickel-free tracker.
Would changing the band make Ray suitable for a nickel allergy?
No. Changing the band does not change the stainless-steel case. Do not use Ray if you have a nickel allergy, regardless of the band you choose.
For general band compatibility, see bands and sizing. If you have another question about Ray's materials before ordering, contact us.
