Thanks, it was very useful! I was undecided whether buying drawers online for my kallax, the IKEA website doesn't describe the structure as well as this video! I'm definitely going to purchase one 💪
The tool that you used to mark for how deep the insert needs to be. Did that come with the drawers? Mine doesn't have anything that looks like that. If it didn't, where did you get it, or what is the measurement for the depth mark?
