Each puzzle piece is a unique organic shape and compared to the traditional puzzle piece shapes, these pieces have proven throughout our testing to make it easier for people to find, hold, and try the puzzle pieces in different positions on the backboard, causing the least amount of anxiety. Each puzzle's subject has been carefully selected to provoke conversation, stories and memories - strong images with a more human touch. The image is printed directly onto the puzzle so that it cannot be peeled off. Each puzzle is made of plastic as plastic is more durable than equivalent puzzle materials. When looked after our plastic puzzles can last for over two years, with regular use. Plastic also meets infection control standards, can be easily cleaned, and is stain-resistant.
