Set of 5, size 6. Approximately 18.5 cm long. I bought a large quantity of brushes because I planned to use them with a large group, but I ended up with a lot left over. Please note that these are not high-end products. Some of the brush tips are slanted. (They returned to normal when used) They will be delivered in simple packaging. Some bending may occur during transportation. These items have been stored at home, and there may be minor scratches or stains in addition to what is shown in the photos. Please refrain from purchasing if you are concerned about minor details. Please read the self-introduction and agree to the terms before purchasing.
