Last year I brought a bunch of stuff off Wish and included in that lot was a couple of sets of paint brushes. I think the total cost of these brushes was about NZD$10.00. Normally I buy Games Workshop brushes but they are pushing $10 each now. I have tried $2 Shop (I guess Dollar Store or Pound Store to you Yanks and Poms) brushes with varying amounts of success and failure so was not holding out too much hope for these Wish brushes.
I have been pleasantly surprised. Already painted three units with the first of them and have had no problems. For the price I am not too worried about how long they last but with normal maintenance I think they will surprise me.
