10 mm and 8 mm magnet cartridges

These cartridges will fit in the Magnet Holder Box by mattathawy. 

Standing on the shoulders of giants (gabriel.poleze, Zenius and mattahway), I could not see any cartridges for 10 mm or 8 mm magnets, and those critters can be just as evasive as the smaller ones. Since the original cartridges (love the idea, by the way) are too narrow for the bigger magnets, I decided to try double-barreled cartridges, and I like the result.

Most of you probably only need one, by the way. The 10 mm version holds 45 of the 2 mm variant, the 8 mm version 75.

The new version has slightly bigger holes, because the magnets were sitting a little too snug.
