I have purchased the orange and pink sets. I've attached samples for both sets and two drawings created with those nibs, one with pencil shading and one solely in ink. I'm very, very pleased with these! They're really nice to work with, and are as good as some nibs I have bought from Japan. They came really quickly, too, considering the fact that I placed the order on Feb 12th and received it on March 17th in Romania, when the outbreak started affecting not only China but my home country, too. I highly recommend these!
It arrived in only one month. Soon, I'll send photos on practical aspect of these nib pens. Thank you, seller. I recommend this product.
