Very disappointed to receive this. For the most part this is truly a five star case and practically as good in quality and construction as almost any semi-rigid EVA case from any brand/vendor that sells it. Unfortunately, the dimensions given are far removed from this type. At the very top it clearly says it's 12 x 12, and then at the bottom of the page it says both 12 x 12 and something smaller and rectangular. I skipped that last part and unfortunately the case was so much smaller that it didn't fit the item I bought it for. I bought two more cases and (surprise?) those sizes were also very wrong. If you want this for something other than the two drill models listed and think it might be close to the maximum space allowed, note that those dimensions are already a bit large and look for a larger case instead. Other than that it's a good work bag, the zips aren't the best but they're decent and the stitching is average and well done. The yellow color is quite light when opened and the straps are a different shade from the zipper and pocket. When it matters. But it's definitely a rectangle, and slightly smaller than the hidden rectangular dimensions listed here.
