These glass chopping boards have been decorated using a technique called reverse decoupage.  This is where you apply decoupage materials (like patterned paper or napkins) to the backside of a glass surface, creating a design that appears to be on the front when viewed through the glass. 
 
The chopping board has been decoupaged, painted 3 times and varnished 3 times for the upmost protection.  Please do not emerse in water and soak as this may damage the design.  Simply wipe clean.
 
Each board measures measures 30cm x 20cm and includes protective feet underneath.
