Aside from being a beautiful design, you'll also have the perfect conversation starter around your neck. Ask any math lover and they'll quickly point out that the nautilus shell is the perfect example of the Fibonacci sequence, a mathematical way to explain the geometry of shapes found in nature. This 2.5 inch necklace has another hidden secret, flip it over to expose a mini dabber tucked away in the back. The wearable design means you'll never forget your metal dab tool (or the Fibonacci sequence) ever again! Made of durable metal, the cool dab tool goes perfectly with a portable dab rig and makes handling difficult concentrates a breeze.
