THIS IS A VERY SIMPLE TEST MODEL. IT IS THE FIRST RING (Size 7) DESIGN CREATED BY SACREDLIFE ARTS MERELY MADE FOR SIZING PURPOSES. MAKING SURE OUR RING SIZES ARE CORRECT IS THE FIRST KEY TO DESIGNING QUALITY RINGS... SO THIS IS A "TRIAL AND ERROR" PRODUCT. **Note: Any model that has a 'FIRST TO TRY' icon is in the experimental printing stage. This means that ordering this model will send it into the "FIRST" test for 3D printing for your chosen material. There can be very rare instances where the model must be updated in order to complete the 3D printing process. If this is the case, you will be notified that your order was canceled and must be placed again. This occurs to allow you to re-approve the updated version of the chosen model before being charged for anything.**
