Thank you for viewing! 10 pink & 10 blue This is a set of 20 heat-erasable marking pen refills. * Color changes for the refills are also possible. As these are imported goods, although they are unused, the quality may not be as high as that of Japanese products. Thank you for your understanding. m(*_ _)m Shipping will be via regular mail, so it may take some time to arrive. ⚠️《《Attention》》 Regular mail is not delivered on weekends and holidays. It seems that it can sometimes take more than a week. If you are concerned, we recommend using Mercari delivery! If you would like to use Yu-Yu Mercari delivery, it can be changed for an additional 80 yen, so please let me know in the comments.
