かぶれた
後で判明したがアマゾンとその他で1000円近く値段が違う。類似の商品にも出て来なかった。 ２４時間装着とあったので着けて寝たら、かぶれでしまった。本商品とは素材が違うが、高いので怖くて買えない

Oura Ring cannot be delivered to some locations.
Great sizing tool. However, Amazon SG doesnt allow the actual Oura Ring to be delivered. The status has been “Ordered Received…”

Buy the kit. It will give you sizing peace of mind!
This little sizing kit works great. Was able to get the correct size. I decided to wear the size I wanted from the kit for a few days to make sure it fit well when my hands changed throughout the day. When I finally purchased my Oura ring I had the perfect size. No issues at all.
