Every figure below is a manufacturer specification read off the listing itself. The judgments are ours.

What the specification says

1,400 × 6 × 0.65 mm (55.1 × 0.24 × 0.03 in), 6 teeth per inch, alloy steel, five per pack. No EAN on the listing, and the part number field contains an unrelated string — a listing defect rather than a product one, but worth knowing.

Width against radius

That is the whole decision on a band saw blade for curves. Wider blades cut straighter and follow gentler curves; narrower blades follow tight ones and wander on a straight cut. 6 mm (0.24 in) is the practical narrow end for a small machine.

What comes up most often

How tight a curve will 6 mm (0.24 in) follow?

Roughly a 20 mm (0.79 in) radius. The rule is that blade width sets the minimum radius, because the back of the blade has to swing inside the kerf: 6 mm (0.24 in) follows about 20 mm (0.79 in), 10 mm (0.39 in) about 40 mm (1.57 in), 13 mm (0.51 in) about 60 mm (2.36 in). Forcing a wide blade round a tight curve twists it and it breaks.

Why buy five?

Because narrow blades break. They are thin, they run at high tension, and a moment of forcing a curve or a blade that has been re-tensioned too often ends the same way. A pack of five is a year of curve cutting for most workshops.
