rOtring Tikky Exam Standard Premium Large Pencil Erasers - Box of 24 Rubbers - Clean Dust Free Erasing

I bought a rOtring pencil and was very impressed with the quality of the rubber at the end of the pencil however was shocked to find out it was ~£10 for 5. I decided to purchase these and was very shocked of how amazingly it rubs out. Every other rubber I have barely rubs the lead while leaving ugly bits all over the page. This rubber does leave residue however it does not stick to the page nor is hard to clean. Would recommend.
