Wholesale Seashell Coasters - Mason Jar Lid, Coastal & Beachy, Resin

Seashell Coasters handcrafted inside gold wide-mouth mason jar lids, featuring real sand, starfish (sea stars), abalone shell pieces, scallops, and assorted ocean treasures suspended in crystal-clear resin. Perfect for coastal gift shops, beach boutiques, aquarium stores, nautical décor sections, and vacation destination retail. These coastal resin coasters bring authentic beach décor to tabletops while offering a unique, conversation-starting design. Each coaster begins with a layer of real sand, carefully arranged with hand-selected shells and sea life. I then seal everything in plant-based, non-toxic resin, creating a waterproof, durable finish with a subtle blue mica shimmer that enhances the natural detail of every shell. The mason jar lid design provides a built-in metal rim that acts as a lip to help contain condensation and prevent moisture from spilling onto surfaces.

Because each piece is individually arranged by hand, no two coasters are exactly alike — making every one a small, functional piece of ocean art customers love to gift or collect.
