ᐅ 2-shelf unit similar to the Ikea Expedit system

Hi
About a year ago, I bought a shelving unit from IKEA. It consists of 2 squares and looks like an Expedit shelf. The difference is that nowadays, they only come with at least 4 squares, but I am still looking for one with 2. Did the shelf have a different name, or was it just a version that was made in the past and is no longer available?

The shelf you mentioned was called "HAJDEBY" and was offered as a limited-time promotional item during the "Fantastic Tuesday" event. In other words, it was part of a special promotion and is no longer available through IKEA.

Hi, thanks, that's exactly what they look like, but there are two joined together, not two separate ones.
