4" x 4" Square Slate Coaster – Custom Laser Engraved

Bring natural stone texture and custom design together with this 4" x 4" square slate coaster, crafted from genuine charcoal-gray slate and engineered for crisp, high-contrast laser engraving. Each piece has its own subtle color shifts, layered texture, and organic chipped edges, so no two coasters look exactly the same.

• Clean, detailed engraving area: A generous 3.5" x 3.5" engravable surface is ideal for monograms, names, corporate logos, event branding, or simple line art.
• Durable, food-safe finish: Coated with a food-safe, scratch-resistant seal that protects the stone while preserving its raw, rustic slate appearance.
• Protects your furniture: Four foam pads on the underside keep the coaster stable and help guard tabletops, bars, and counters against scratches and slipping.
• Flexible personalization: Choose laser-engraved text, artwork, or logos, with custom placement inside the 3.5" x 3.5" engraving zone for single coasters or coordinated sets.
• Versatile use cases: Works as a personalized gift, branded barware for restaurants and breweries, corporate giveaways, or everyday home and kitchen décor.

Whether you’re building a refined home bar setup or creating custom engraved coasters for clients and events, this square slate coaster combines rustic character with long-lasting functionality.
