The range of scales covered on the ruler is very good, and the different colours on each side of the ruler help when switching between scales. It is a bit plastic and feels quite delicate, i don’t know how long it would last in regular use. Perfectly usable for occasional and beginner use, but store carefully and don’t drop as the pointed corners are delicate, and If they get damaged it’s not a lot of use. Worth noting no storage case provided. Good value for the price. Helix make an aluminium version also available from amazon of this but it’s nearly twice the price, but worth considering if you need a more durable option. ## Frequently Bought Together - Helix 300mm Metric Triangular Scale Ruler, Red - Silvine A3 Graph Pad. 50 Sheets of Quality 90gsm Paper, Printed 1-5-10mm Graph.
