RE: Hohner harp cases have lasted well.
It is a sad day when (after vinegar, WD40, super-glue with plastic-store-bags) it is time to lay a Hohner to rest. I morn the day with disposal into the waste-can (not knowing wether it is brown/blue/green)but some missing notes - no longer have a "work around."
Unfortunately, it appears you are laying your instrument in the grave along with their casket, a holder lasts longer than the instrument and (some of my cardboard cases AND sueade leather containers) are still intact and holding another generation of "suck-blow-holes."
