What a brilliant product, these are excellent because;

Store them in the smallest of spaces
Excellent for travel on flights or in cars

can re-use them
make - aminals, flowers, people, dinosaurs, jewellery, huts, camps, pictures (on the flat board), 3D shapes, have creative competitions at parties, etc, etc.
They are like the old-fashioned pipe-cleaners, except they stick to each other along their length, as well as bending into any shape.
My kids have played with them for months now - they also make a great party gift. - I bet you won't be able to resist making something yourself!
