Or who is at least willing to take the big ones off my hands in exchange for shipping so I have cupboard space for more smaller ones?
It would be silly to throw them out, at this point, since they are still in perfect working order, but I really do not get along with them at all.
I’m in Germany, for shipping and all.
I also have a spare small (i.e. 600 ml) one, bit thinner and taller than the plennyshake standard, with no visible branding, a white lid and round metal whisk thingy instead of the sieve-like lid insert, which for some reason could cope with the old formula, but absolutely cannot not with the new Active one, clumps galore - which I’d happily throw in as well if there’s interest.
Perhaps consider giving them away to friends or family members or even something like salvation army or thrift shops. Good luck! <3
