Hi I want to buy a rechargeable eraser
but have read it's not easy to get them these days.
The review on uTube about the Staedler Mars one says it doesn't hold the rubber tightly.
However I see Staedler also have one called 52701. Does anyone know if this is the improved version or the Mars one repackaged & if it's any good
? Any other suggestion too please. It's a lot of money to spend if I don't get it right. I'll have to purchase on-line as I can't find anything for sale here in Australia.
