🌲 SpruceGrip™ Spill-Proof Coffee Coaster & Mug Carrier

Transforming Coaster with Handle | Nature-Inspired Design

Meet SpruceGrip™ Spill-Proof Coffee Coaster & Mug Carrier, a beautifully engineered drink accessory inspired by the natural form of a tree log slice. What looks like a rustic wooden coaster transforms in seconds into a secure coffee carrier — designed to dramatically reduce spills while you move.

Blending smart mechanics, physics, and craftsmanship, SpruceGrip™ turns your everyday coffee moment into an experience worth talking about.

From Coaster to Carrier — How It Works

At rest, SpruceGrip™ functions as a stylish coaster. When needed, the textured “bark” smoothly unrolls into an ergonomic handle, allowing you to lift and carry your mug with confidence.

• Print-in-place articulating hinges
• Smooth unrolling bark mechanism
• 90° rotating hinge locks the handle upright
• Comfortable grip for one-hand carrying

No assembly. No loose parts. Just smart design.

Spill-Proof by Engineering, Not Guesswork

SpruceGrip™ isn’t spill-resistant by chance — it’s spill-proof by design.

Through precise geometry and physics, the handle’s center of mass aligns perfectly with your mug’s center, helping keep your drink level while you walk. As you move, centrifugal force naturally stabilizes the mug, reducing tipping and sudden sloshing.

An included stretchy support band (hair tie) adds shock absorption, dampening movement and keeping your drink steady even on the go.

Built Through Iteration & Precision

This isn’t a novelty gimmick. Over 50 design iterations were required to perfect the articulating hinges and gravity-lock mechanism. The final result delivers:

• Smooth, natural movement
• Reliable locking action
• Durable, repeatable performance

Every motion feels intentional — because it is.
