Finally we are seeing some nice tube fly boxes coming onto the market and Snowbee seems to recognize the need. 
 Here is Snowbee's new Tube Fly Box
this is the large size..able to handle 21 large Intruder style  Tube flies and 14 smaller ones
     
The Snowbee Design is without doubt the most logical of all the attempts to find a management system for Tube Flies.

Why Tube Flies...,Because they catch fish!
