The cup holder area has a visor, the same as used in the brim of a baseball cap, that holds cups and other objects tight in place. The back panel is also rigid, giving it an overall firm shape and stability. Thanks to YKK SNAD fitting solution, this cup holder can easily be installed without any tools and can be removed when not in use. 

The depth is approximately 11cm (4.3 inches), which is enough to comfortably fit a standard water bottle or tumbler (8cm / 3.1inches in diameter). The bottom has a mesh panel, so there is no need to worry about condensation or other debris accumulating and soaking the interior. Acrylic material itself is a mold-resistant material, so it’s less likely to be stained (Still, when storing the cup holder, rinse well to remove salt, and dry it well).

Size: 8.5cm in diameter, D 11cm, H 15cm, W 12.5cm
