Trap Dri Mini Flow
The new unique mini flow system has been designed with sealed sheepskin/hide bag etc players in mind.
The unique slimline construction allows these bad boys to slip through a split stock to be fitted into Drones of non zipper bags.
Set of 3 for each drone.
Utilizing only a small amount of silica gel these are very cost effective to run.
Can also be used in synthetic bags zipper or non zipper.

TOP SOLO PIPER ALLAN RUSSELL GIVES TRAPDRI MINI FLOW GLOWING RECOMMENDATION -
" Been playing the mini flow cartridges. Played for an hour and a half and there was no moisture on the reeds or inside the drones. I find they are well worth the effort to fit to increase the playing time , will be good to get longer practice time as usually I get beads of moisture on the reeds after 45 mins, modern drone reeds have improved things but the new Mini Flow System is much better, I would recommend these to anyone"
