This custom Signature Collection hourglass is handcrafted from solid walnut grown in the United States. Light to dark brown in color, this wood has a fine, open grain and a smooth finish. Combined with glass bulbs hand-blown in England, this classic piece adds a striking accent to any room. Key Features Wood construction Fillable globe Specifications Offered in 3 sizes - 4"D x 6"H, 6"D x 10"H or 8"D x 12"H (size approximate as globes are handblown and frame built around them) Available fully assembled (as shown) or in kit form. Fully assembled have 5 or 15 minute timers in the 4x6 size, 60 or 50 minutes in the 6x10 size, and 60 minutes in the 8x12 size. Kits are available with two options: You assemble, no sand - for customers who want to add their own sand (i.e. two different colors). Note: globe provided has a larger hole to accommodate different types of sand so timer accuracy is not ensured. You assemble, sand included - for customers who want a more accurate hourglass. The natural sand you see pictured comes with your kit (not available with all options). Made when ordered, usually arrives within 2 weeks.
