Many times we read books by their covers, and when we see made in ... we immediately catalog things.
I got two erasers, both from Staedtler, both very similar looking, similar in size, shape, not so much in color or country of origin
On the left, in pink it is the Staedtler 526F C53 and on the right in yellow the Staedtler 526 35. One born in Germany while the other in Thailand.
Both erasers came in a plastic wrap, while the protective cover of the pink one can be used as a protective cover. Both erasers have the Staedtler logo on them, even though it's more visible on the pink one as it is a deeper embossing.
The simple test consists of erasing a softer 4B lead and a more standard HB polymer lead.
And here are the results of the test. Both did a good job, especially on the polymer lead. The 4B was a little bit trickier. The German is more prone to smudging and feels a bit sticky. And this is seen on the eraser as it gets dirty, especially after using it on the 4B lead.
On the other hand, the Thai is crumbling a bit more while erasing, keeping it cleaner.
I can not say that one is a clear winner, as they both did well in certain areas. The German was a hair better at writing and lines, but because the Thai crumbles more it was more effective in the areas where there were a lot of pencil marks.
Taking a look at the eraser dust it's clear that the German sheds less, and usually in finner dust that the Thai.
Congrats to both fighters for doing a good job. On the left the Pink German Staedtler 526F C53 and on the right the Yellow Thai Staedtler 526 35
