The Factis 60 RP and the Ty Peepers (unboxed)
Post offices in the UK sell all sorts of things and the things they sell are often quite reasonably priced. This can include things like cakes, hand bags or kitchen foil, but naturally there is also a selection of stationery available. In July I bought the Factis 60 RP eraser at the Cinnamon Hill post office in Walton-le-Dale for 25p (~39¢; 32c). I have seen Factis erasers in Germany, too. It is often not possible to identify the manufacturer of these erasers, but I assume many of them are made by Factis. I assume the company is named after one of the components needed to make natural rubber erasers.
The Staedtler 1810 KP72 and the two erasers
Another eraser I bought in July is the Ty Beanie Puzzle Eraser Peepers. When I saw a selection of the Beanie Puzzle Erasers on the MS Pride of Rotterdam I remembered Shangching’s positive review and bought one for £1.19 (~$1.87; €1.50). There were many erasers to choose from, so I picked Peepers, the duck, one of the erasers with a more complex looking surface structure.
The Factis 60 RP and the Ty Peepers taken apart
Performance-wise both erasers perform similarly well, with the more rubbery 60 RP needing a little bit less effort to eraser graphite than the Peepers. Both erasers perform worse than a good eraser, like my favourite non-dust erasers or the Mars plastic stick 528 55, but better than the typical non-name eraser or the most erasers you’ll find at the end of an eraser-tipped pencil.
Comparison of the Factis 60 RP and the Ty Peepers
You can find out more about Factis on the Eraser World web site.
I bought the Staedtler pencil with the mathematical formulas, the 1810 KP72, used in the photos and for the comparison in Nuremberg’s Staedtler Welt for 95 cents (~$1.18; 75p).
