The round discs are: Large- 1" across, Small- 1/2" across, attached to a stainless steel chain.
COORDINATES: The length of the coordinates is limited to 6 numbers for them to fit onto the disc. If you need help attaining coordinates, go here: http://itouchmap.com/latlong.html
MATERIAL: The round discs are made of aluminum which is a lightweight, soft, pliable, yet sturdy thick metal. There is a much lower rate of skin reaction with aluminum than with sterling silver. It will never tarnish, discolor or rust. It does not leave green marks on your skin like other metals. Aluminum is a metal that is easy to maintain. It polishes to a nice shine with a polishing cloth.
✱Please remember that we hand stamp each necklace so there may be some slight variations. Sometimes not all letters and/or numbers will be perfectly aligned as this is the nature of hand stamping. This adds character and uniqueness to your items. We do try our best though to achieve that perfect and straight look :)
