This small box holds a dozen random flies of various sizes and patterns. These will include odds and ends, tried-and-true originals, or ones I'm testing out. The last time I sold a mystery dozen, the recipient caught 21 fish in an outing on one of the patterns in it. 
 
A box includes your choice of standard flies, euro nymphing flies, or a combination of both. Averages $1.25 per fly. Free shipping.
