Stickle Bricks are a construction toy primarily intended for toddlers invented by Denys Fisher. The brand is owned by Hasbro and they are currently manufactured by Flair Leisure Products plc. An individual stickle brick is a colourful plastic shape a few centimeters long which has a brush of small plastic fingers on one or more edges. The fingers of adjacent stickle bricks can interlock, allowing them to be joined in various ways. Several companies manufacture similar toys, not all of them compatible. Names for these toys include Nopper, Bristle Blocks, Fun Bricks, Clipo, Krinkles and Thistle Blocks.
