Otto Frei Aufbewahrungsbehälter für Bohrerbox aus Kunststoff

Good idea, but has a slight design problem in that it seems to be precisely dimensioned for Busch or other German made burrs. Those boxes slide into the slots nicely. A little friction, but they fit. Swiss burrs, on the other hand, perhaps because some of them have a label that extends around the sides, fit a bit too tightly. Can't get the bur boxes all the way in, especially at the ends of these things. And in another oddity, I'd ordered a bunch of the Fox brand burs. Otto Frei sent them packaged in what looked like these smaller boxes in this item, but they were only similar. Not quite the same. A little frustrating/confusing, though not really an issue. But I wish these things were a hair looser in fit, so bur boxes slid easily in and out no matter which manufacturer.
