Miyou-sama, 6 plus 1 Please let me know the color of the bonus. Thank you for looking. I received these from the soroban (abacus) class my child attended. There are 11 in total: purple 3 + yellow 2 + green 2 + red 2 + pink 1 + light blue 1. The lead inside is all black. There are 8 leads in one stick. The length of one stick is about 10 cm, which I think is just right for toddlers to elementary school students to hold while using the soroban. I checked that the new leads are sharp by taking them out one by one. (I think I've checked them all, but I'm sorry if any are broken.) I am cleaning them with disinfecting wipes while inspecting them, but they are used items, and I have taken out the leads for inspection. Please understand. They will be shipped in a Yu-Packet Post mini envelope and delivered to your post box. If you think the number is a bit high... please feel free to consult with me in the comments. I will handle it for 50 yen per stick (6 or more required) + 1 bonus stick.
