We are a boutique product developer and manufacturer from the Pacific Northwest that includes some of the friendliest talent from around the Seattle metro area.

Founded in 2013, Stonevale Products initially developed a soda preservation cap which was followed by the Everwine wine preservation system.

From concept to finished product, we design, prototype, manufacture, and retail new products to customers worldwide.

Many of our products have earned patents in countries around the world which helps to ensure a consistent, quality product you can trust.
