My son’s rather battered school bag was disposed of at the end of the school year. No remaining pens/pencils, the case was having in by a thread, but this ruler survived and will be returning to school for year 8!

Nice quality aluminium triangular ruler. Be wary though that only one edge has centimetres and they go from left to right only. The other edges have different scales, 1:50, 1:25: , 1:20, 1:75 and 1:125. This might be great for you if you need those for doing scale drawings, but I would've preferred CM and inches going in both directions.

Solidnie wykonana, wygodna w użyciu linijka. Poprawcie tylko nazwę na poprawną polską, to jest jak wspomniałem "linijka", a nie "zasada"...

Looks on the pictures as though it has inches on it, it doesnt. It has really unusual "ratio" markings which I cant work out.The cms are accurate and it did what I needed it for - a straight cutting edge

I write this review based on my decades of experiences as a consumer and user of this type of item.I needed a replacement for a similar item that I have had for years but mislaid.Cheap at under £3 and delivered promptly. (3 days) in a massive box app 10” deep, 28” wide and 18” in width. No other items. What are they doing?Any way the ruler is marked in both inches and centimetres. It is equalatrilly three edged so that when two edges are on a flat surface the third sits up at 90 degrees.Thus when in place it can be used as a measure whilst still having two free hands.The figures and markings could do with a change to help them stand out against the aluminium coloured finish of the ruler.It’s shape makes it sturdy so I anticipate being able to use it for years
