First Sizing Kits Have Been Shipped

We’ve shipped out the first sizing rings to pre-orderers. We’ve also upgraded to a warehouse that can handle a larger number of orders, as many have wanted to use the ring sizers to find out their size.

We’re sending the sizing kits out from two warehouses: the main hubs are located in Europe and the US. Currently, sizing kits are being delivered from the European warehouse. The estimated shipping start for sizing kits from the US warehouse is at the end of next week. The shipments will continue through May. If you’ve ordered the sizing kit, you’ll get an email notification once the sizing kit is shipped. The page for all your sizing-related information is
