Lost fly box

Lost a little plastic box on Twenty Mile last Tuesday, just noticed it cleaning my vest, box is 3/4" x 2 1/4" x 3 3/8". About a dozen clear bead caddis pupa in it and maybe some Prince nymphs. Will pay postage to have it mailed back to me. Left it on bank on opposite side of creek at first pool from parking lot. Thanks in advance.
