SIZE: 1. 8x12 inches or 20x30 centimeters 2. 11x15 inches or 28x38 centimeters I make glass wall arts and I decided to make cutting boards from my HIGH QUALITY glass. Glass Cutting Board has silicon dots and it rises the glass from bottom. I use tempered glass, so it is safe. It has smooth edges and it protect it from the damages. The wood and plastic cutting boards are not healthy and when you cut something on it, you also cut the cutting board as very small pieces and they mix in the food, so glass cutting board is more useful and healthy. The glass is easy to clean depend on the other cutting board types. PLEASE wash by hands. And glass is also RECYCLABLE and ECO-FRIENDLY rather than wood and plastic. I print the design on the backside of the glass and your food just touch the pure tempered glass surface. CUSTOMIZE: I listed many different design and if yu like I can print your own design, writing or image, please just contact me for this. Please contact me for any question and check my FAQ. Thank you
