I saw one of these new Irideus boxes just the other day at Puget Sound Fly Company.
The Tribute tube fly box will hold 44 tube flies of varied size and head shape securely. We have added two rows of foam to provide a hold on loose hooks or a few random spey flies for the day. The foam rows provide 22 hook or fly spaces per row, 88 total for the box.
$29 bones, free shipping.
