Blank signs, so the cabinet can say whatever it needs to say that day. Cloud and cone shapes in blue and red, ready to write on, wipe off and write again when the specials rotate.
Plain signs suit anyone whose flavours move: seasonal specials, one-off batches, a ripple you are trialling on a Saturday. They slot straight into pans in parlour, cafe and van cabinets, and because customers can read the flavour without asking, the queue moves and the pans at the back get noticed. Buy enough to cover a full cabinet plus a few spares, as they have a habit of going missing.
