Our mandrel kits are made from 316 marine grade stainless steel and come 20 mandrels per bag.
There are 3 sizes available:

• Small-fits micro tubes and many Pro Tubes
• Medium-fits most medium tubes such as HMH
• Large-works with large tubes i.e. large saltwater flies

*Please note, some commercially tied flies are tied in a manner that compresses or crushes the tube and may prevent them from fitting on a mandrel. If you have a fly that is not working, please send information to us via our Contact Us link and we will work with the manufacturer to resolve the issue.
