People can not resist playing with these and resorting to their childhood! (7.5 cm) Ideal to put out on the table for people to fiddle instead of doodling - keeps the brain alert and alive. Perfect to stand on the training tables to support the pens plus as a visual demonstration of changing states and how people can feel a bit wobbly when things around them are changing.

Also ideal for holding flipchart markers on the table as a pen pot.

Price per spring.
