Aristo BTS Quick Adjustment Compass (Circles up to 340 mm Diameter, 2 Joints, Leads and Spare Needle) Neon Red

The Aristo BTS quick adjustment compass works precisely and is thus more than meets the high demands in maths and geometry lessons at school and at university. Both legs have a joint. A thigh can accommodate inserts up to 4.0 mm in diameter, e.g. an extension rod or an adapter for drawing with pigment pens or ink pens. The quick adjustment is activated by pressing the two locking knobs and the fine adjustment is done on the middle wheel. When laying aside, the dimensions remain unchanged. With the compass you can draw circles up to 340 mm in diameter. Needle and lead are secured in a non-slip clamp International products have separate terms, are sold from abroad and may differ from local products, including fit, age ratings, and language of product, labeling or instructions.
