High quality storage box for your extra fly lines. Don't have an extra spool for your reel? No problem. Quickly switch and store fly lines with the Switchbox from Omnispool. The spare switchboxes can be purchased separately from the complete Switchbox Kit (which includes the carebox line cleaning attachment and the hand crank).
To use a switchbox, simply feed fly line into the box and attach to the inner spool. Use the hand crank to crank the line off of your fly reel.
