Cleversticks
plastic construction toy manufactured in the UK
Cleversticks is a plastic construction toy manufactured in the UK.
The "Cleversticks Construction System"
The original design manufactured in polypropylene used sticks with pairs of jaws on each end and rings, the jaws connect onto the body of the sticks or rings, The jaws also connected the sticks end to end. The resulting toy was best suited to young children; with these few components, a wide range of models could be assembled. Squares, triangles, rectangles and hexagon shapes were later added to allow the toy to be used for sorting into sets; the toy could now be used in primary education. Technical shapes were added to increase the complexity of the toy and appeal to older children. The most recent additions utilise the new patented design manufactured in Acrylonitrile butadiene styrene (ABS) including wheels with tyres manufactured in Santoprene, a synthetic rubber.

Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
