STAEDTLER Mars® Comfort Precisie-cirkelset met universele adapter, verlenging en vulpotlood, diameter 26,5 cm, 551 02

コンパスに3000円以上、ってなかなか勇気が要る決断でした。それも絵を描くのに…。でも、買って使って分かった、1000円以下の子供用コンパスとは、全然違う。重さがあるので、迷わない、ズレない、カクンと言って中心がズレたりしない！もっと早くに知りたかった✨

Prodotto di qualità.

After struggling with several inexpensive compasses, that jumped around on me, I opted to go with the Staelter comfort compass.It was expensive but I have no regrets.This compass is a joy to use!

Prodotto ottimamente costruito...

OK, I'm biased, I'm a maths teacher, but this 'pair of compasses' is well made, easy to use and very accurate.For those doing their GCSEs, a large bow compass (capable of opening up to a radius of 10cm or more ... these open to over 13cm and with the extension bar an amazing 24 or 25cm!) is a good investment as it enables you to produce neat, accurate answers to the scale drawing, construction and locus questions and avoid losing easy marks on the papers.So often students get the really cheap compasses which easily loosen up, making it almost impossible to achieve the level of accuracy required for full marks. Others get smaller bow compasses which are accurate but cannot draw large enough arcs! Such a shame!The extension bar with this set enables much larger circles to be drawn, but it is not necessary for GCSE Maths - I only bought the set with the extension bar because it was the same price as the set without and I was curious!Rotring also make a reasonable pair of bow compasses the same size as these, and they are much cheaper. They are not quite as easy to use, but I would happily recommend them too.
