Eraser - what am I doing wrong?

i bought some eraser pens from the internet (see picture) as I wanted to create fine details like hair etc. my paintings are golden high flow acrylics on glossy cardboard. However, it’s simply impossible to remove any paint at all - except I force it like a bull, but that’s highly unpractical and impossible to work with. I also realized the eraser pens are rather soft. Do I need a harder type? Electric one? Am I using wrong type of paint?

It might be because of the board your using soaking up the paint to fast to let you erase it, That's why I use translate paper as the paint sits on top and won't soak in like reg paper, it's not the paint I also use golden paint
 
What you should be looking for are the fabercastell eraser pencil #7056 which is the harder of the two common erasers from fabercastell.
To erase effectively you need the right combination of paint, paper and tool to erase.
There are many ways to remove paint from the surface. These include eraser pencils as already mentioned, fiberglass pencils (commonly used for cleaning printed circuit boards or model railway tracks) wooden dowel sharpened to a point and if all else fails the #11 hobby blade.

Erasing will lift your work to the next level but there’s also a learning curve involved so be patient
 
Like what's been said before. Those erasers are not ideal.
The Faber Castel Perfection 7058 is a good one. Not as hard as the classic typewriter ones but good enough from the ones that are easily obtainable. The Staedtler Mars Rasor 526 61 is also good. But paint and paper also plays a big roll. You can not erase thinned paint if the surface is very absorbent.
 
Ah, airbrushing - just when you think it could not get more complicated anymore... so much to learn. Thanks to all to your very valuable replies, extremely helpful!
 
Here is a link to a thread that @AndreZA posted awhile back... great info (as always) and while it doesn’t contain the golden paints that you use you’ll get a better idea how different erasers work on different papers.
As pointed out already your paper can’t be absorbent, the paint needs to sit on top of the paper in order to be erased :)

I actually use those erasers besides the faber castel hard and soft erasers and they are not as soft as the soft faber castel ones but I use them on schoellershammer A4 airbrush paper with etac efx paints and it is like Andre said a matter of the paper or cardboard you are using if it soaks up the paint it will be real hard to erase no matter what eraser you use
 
Golden High Flow was created for run painting not airbrushing plus the addition of a cardboard surface is not helping.

Mix some airbrush medium in with the Golden and also reduce with distilled water. You could use 4012 reducer but the cure time would become so quick you may end up right back at the same spot.

Use a claybord or a canvas with some varnish and sanded smooth. I wouldn’t recommend Synthetic Paper with Golden High Flow.
