Spherical vs. Hourglass: Which GRAV® Pocket Bubbler is Right for You?
The GRAV® Pocket series has revolutionized mobile smoking. But before deciding, many face the question: Spherical or Hourglass? Both are compact (approx. 7.5 cm), use a 10mm joint, and are made of premium borosilicate glass. However, there are subtle differences in detail.
A Quick Comparison
| Feature | Spherical Pocket Bubbler | Hourglass Pocket Bubbler |
| Form Factor | Spherical, futuristic | Slender hourglass silhouette |
| Volume | Slightly larger water volume | More compact design |

The Spherical Bubbler: The Small Powerhouse
The Spherical is for those who want maximum water filtration in a minimal size. Its spherical shape allows for slightly more water than the hourglass version, providing a touch more cooling. It's the perfect choice if you're a fan of classic, clean designs and are looking for a device that feels like a small hand-charmer.

The Hourglass Bubbler: Elegance Meets Function
The Hourglass (especially in Pink) is an optical highlight. Its biggest functional advantage is the "wasp waist": This constriction acts as a natural particle filter and splash guard. If you tend to draw a bit harder, you'll never get water in your mouth with the Hourglass. In addition, its shape offers an extremely secure grip for your fingertips.

Our Conclusion
- Choose the Spherical if you want maximum cooling in the smallest space and love the clean design of clear glass.
- Choose the Hourglass if aesthetics and an absolutely splash-free experience are important to you – especially in the pink edition, it's a real eye-catcher.
