Question about Weible Map holder

The arc is 50 cm long. Because of the bend, the direct length ("as the crow flies") from one end to the other is approx. 46.5 cm. The card holders are constantly in use with our three children aged 4-8. We can only recommend buying them.

The information from STGBasel fits. I can highly recommend the holder for children.

STGBasel's answer is absolutely correct.
