I have enquired from Grace Gallant. But perhaps some Flamingo owners on this forum already know from experience.
Also, whether Brompton sells the minimalist female part of thd frame for home-made bags where the frame is not needed. I do nit ser it on the Brompton website.
BTW, as far as I can tell there is no Flamingo website selling parts and accessories. Do Taiwanese Flamingo owners buy everything from brick and mortar shops? Makes it incredibly inconvenient for users eleswhere!
