These float storage tubes are 5.5cm (internal diameter) x 45cm (internal length)
Total length is 47cm, and have a side wall of 2mm (very strong)
Both ends have an end caps which has a double O ring to keep it secure and internal padding,
It come with an internal structure if you want to really secure your floats for transportation but that limits the number of floats (6x 10gram model)
Without the structure you can stuff quite a few in there, in the photos I have shown 10x the 6gram and 6x 20gram.
Also comes with a felt material bag with drawstring,
