Helix Oxford Eco Wiskunde Set - Blauw

Las piezas son totalmente opacas, lo que impide ver las líneas a través de ellas. Su utilidad se reduce sobre todo en el transportador de ángulos, ya que si los lados no sobresalen de este, no es posible medir los ángulos. No sería demasiado grave si no fuera un kit dirigido a niños que están aprendiendo a usar las herramientas. En este sentido, el kit original (el que no es "eco") está bastante mejor conseguido.

Bought for my sister, wanted to get a different colour since everyone has the standard silver tin, looks great

Does the job

I wish I'd looked more closely at the images of this product - it's clear to see. The set squares and protractor in the 'eco' set are opaque. This make their use very difficult (especially with the protractor) and is a design decision that shows little understanding of everyday use of these things.As a maths specialist my advice is to get transparent kit, even if that means avoiding the recycled plastics of this set. A shame but there's little point in having 'eco' kit that doesn't do the job it should.

Most elements are fine but the protractor is opaque rather than see through making it almost impossible to measure angles with it. Seems a rather obvious and major failing.
