Boots, W H Smith and Woolworths all sold geometry sets, some their own brand. You could buy the basic set in a tin as well as more deluxe sets with zipper cases or clamshell style I think this is the perfect eraser. It cleanly lifts off graphite, is non smudgy and is firm enough that you can use a scalpel to carve it into a point to erase tiny details. I’m not a fan of coloured or putty erasers.

Helix is the most well-known name in mathematical instruments and geometry sets for children. Their famous 'Oxford Set of Mathematical Instruments' is still Most children today are familiar with a geometry set in a tin. The sets contain a ruler, a protractor, set squares, a pair compasses, pencils, a pencil sharpener and an eraser.
