As far as blister packs, yeah that's kinda weird...
I agree it does seem strange given the established harmonica sales process.
Usually blister packs are used for very low-end, low-value, low-priced instruments or novelty items such as plastic recorders and Jaws harps. Introducing BP to a long established lineup of iconic musical instruments does NOT enhance one's perception of Hohner's quality nor value.
