I have a number of Phonak hearing aid domes to offer, as shown in photo, none of them have been used previously !
There are 2 unopened packs (10 in each) of Vented Domes 4.0.S and a part pack of same size, ( 6 domes unused )
There is also a part pack (8 unused domes) of Open Domes 4.0.M
Happy to split !! Could possibly post them if that would be of help to you
