Stickle Bricks are a construction toy primarily intended for toddlers. They are manufactured by Playskool.
An individual stickle brick is a colorful 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. Standard sets of stickle bricks contain triangular, square and rectangular pieces. Most sets also include other types of pieces such as heads, wheels and teddy bear shapes.
Several companies manufacture similar toys, not all of them compatible. Names for these toys include "Bristle Blocks", "Clipo", "Krinkles" and "Thistle Blocks".
