I bought Lapp cable and they had to be per reel.
Indeed the nr of meters per reel differ per diameter, the 0,75 and 0,5m
2 went per 100m but the smaller diameter 0,25mm
2 went per 250m

Anyway since these distances are not handy to have in your shack, I bought empty reels at Conrad and wound them with an accudrill and DIY jig.
Edit I am on holiday so can not take a picture, this is from three years ago, in the mean time it is almost full
