shelving system for back wall in the garage

That would also interest me

Could you maybe just post the appropriate Google keywords or the name of the product here?

I share the wish.

I can gladly do that, just google Ordnung im Haus: Regale und Regalsysteme, or also Ordnung im Haus Regalsystem classic. However, I would like to point out that this is not advertising on my part from which I would benefit.

Thank you.

Basically, it’s something like what every hardware store has in their range. We used it to build a flexible shelf in the bathroom where we stored laundry detergent, towels, toilet paper, and so on.

I have to admit, I was expecting something "more interesting." :-)
