Any item you see here is $15 shipped USPS Priority, that is basically shipping plus $5.
Neutrik adapter and Furutech 2.5mm connector are sold.
I do not foresee using these, do not remember why I have some, but do not want to throw them away and in a purging mood. The Furutech 2.5mm and the tube adapters are unused.
Message me if interested.
