VÍDA RING - HOW IT WORKS
The engagement ring is worn together with its stainless core throughout the engagement.
When it's time for you to unite your engagement and wedding rings, use the oval key to unscrew and remove the core. Hold the engagement ring in one hand and with the other slide the key into the slots in the core. Twist the ring and core apart in a counterclockwise direction.
Once separated from its core, twist the engagement ring onto the wedding ring in a clockwise direction.
Twist both engagement and wedding rings together until there is no gap between the rings.
Insert the oval key into the slots in the wedding ring and twist clockwise to tighten the two rings together.
