These coasters are made from eco-boards. Eco-boards are excellent alternatives to plywood and are made of recycled multi-layer single use plastics majorly used in packaging by the FMCG and pharma companies. Eco-boards are corrosion proof, fire proof, water proof and termite resistant.
They come in a pack of 4. Other than adding decorative value to your table, they are an excellent gifting option too!
