Isomars Adjustable Set Square 10" Combo with Triangular No.4, and Flexible Curve

I use this for wood work.. There is a gap Between the detachable head and the Zeero on the scale, I modified it by Screwing a Measured Wood piece, so that the Zeero Corresponds to the edge of the wood that i am Measuring.

I found this equal to Staedtler Mars Penclis of the same looks...good quality and value for money

It's really handy for Archi students..Detachable head works really well and it is still tight after around 1 year of use..Con-Markings are not permanent.. it starts to wear off on 6th month only...Right now after one year of use... There's no marking left...So I use it as a tool to cut boards for model making only bcoz of its detachable head it makes the job easier.

Thanks to isomars for helping our precision drawing folks. The build is commendable and may exceed foreign brands like rotring or staedler.

Isomars is a well known brand for architectural/engineering drawing instruments. You can trust it any day. Scales provided are- 1:10, 1:100, 1:20, 1:200, 1:25, 1:250, 1:50, 1:500, 1:75, 1:750, 1:125, 1:1250.Comfortable to use. Durable material.

Recieved the order properly, but I doubt it's original or a copy... Bcz there is no logo or any mark of isomars on pencil.

Pretty accurate. The scale matches other scales with me. The fitting of the T top to the plastic scale sits snugly to give a perfect right angle. Length is nearly 80 cm, sufficient for my needs. Pretty happy with this product. The cover is suitable.SInce it is a long plastic scale, it is advised to avoid any impact to prevent it from breakage

The product I received does not correspond to the one shown in the pictures. The lead clamping system is different so one cannot use it for shorter leads like broken watercolor pencil which was the main reason for me to buy it!
