These are from a pallet auction for unrelated stuff - looks like it’s from an audiology clinic that might have been closed down.
There are a total of 26 Signia MiniReceiver 2.0: Full sets for each power level and wire length.
And a total of 46 packs of Click Sleeves and Domes.
Asking for USD $250 for the whole lot.
Free shipping in Canada. For US customers, I will do my best to label it such that it gets into the US without custom charges.
