Needles & Grooves

Not that I have seen. There are some options at Target that work (and what I use), but the most they go up to is 3x3. Cube Shelving : Target

Waited almost 2 months for my newest Kallaxes. D:

Just got a 3x3 a week ago and had to rush down there to grab it as soon as my phone alerted me that they were back in stock. Major shortages for sure.

I’ve seen these in Walmart and they look exactly the same. They have all the usual Kallax sizes.

I have a pair of the 2x3 Better Homes and Gardens ones, and they haven't had any problems in the almost 2 years I've had them.

Search “Threshold cube” on Target.com

Yeah I got one at target recently that’s just 2 and it works just as good as my Kallax shelves (but those are 4 cubes each). Also yes Ikea is super delayed. I bought a handful of stuff from them recently, nothing big or major at all, and it took over a month.
