20 Arithmetic bead string
red/blue

Arithmetic Bead String (approx. 45 cm) with 20 balls, which are threaded in steps of 5 on a tear-resistant, stretchable cord. The balls are made of RE-Plastic and have a diameter of 10 mm. When the string is pulled, the light ball lock is released and all the beads slip back together.

Since the balls have the exact diameter of 1 cm, they are also suitable for calculating and measuring.

RE-Plastic is 100% post-consumer recycled plastic which is 100% recyclable again.

Packed in a RE-Plastic-bag.
