In collaboration with our partners at Sitka Gear, we are offering a very limited number of 200 co-branded calls for 2018. Each call is hand numbered (1/200, 2/200...) in the inside of the insert along with the date. They will all be featured as our No. 1 single reed call model. The black pearl inserts are free of any engraving. Our “737” logo is opposite the Sitka logo in black on the orange pearl barrel.
