Set of 4 & Protective Bumpers: Each package contains 4 natural agate coasters with a total weight of approximately 0.85 lbs. We include clear rubber bumpers; please apply them to the bottom to ensure a firm grip and to shield furniture surfaces from potential scratches. Versatile Size: These 4-5" agate slices provide a spacious base for whiskey glasses and mugs. Beyond drinkware, they function as decorative display bases for small candles, jewelry, or mineral specimens on your nightstand or coffee table. Natural Brazil Agate Detail: Precision-cut and polished from natural Brazil geode stones, each piece showcases a neat top surface with the original rough crust rim preserved. This balance of polished and raw textures highlights the stone's organic mineral beauty. Non-Porous & Stain-Resistant: These solid stones feature a non-porous surface that prevents liquids from soaking through. Spills from coffee or wine remain on the polished top and can be wiped clean with a damp cloth, keeping the surface pristine. Natural Variation: As these are natural earth-mined stones, colors, patterns, and exact shapes vary from the photos. This variation is typical of geode slices, making each set a unique treasure for housewarmings or mineral collections.
