Do not use Jerry's Artarama. Use Utrecht or Blick Art. I recently purchased #10 and #16 oil brushes. Upon receiving, I was shocked how small these brushes were compared to my other brand brushes of the same sizes. I wanted to return because of the unacceptable small size. They wouldn't provide a return label. They kept on saying that manufacturers can make whatever they want and label them as whatever sizes. Obviously, they make the price cheap for Artarama but send items that are not up to standard. So many Artarama products are like that. If the price seems good, be aware. Compare the three #10 brushes. The smallest one is from Artarama. They will send you sub-standard items.
