Thank you for viewing! This is a set of 6 pens that can be written on plastic wrap. They have been stored with little use, and I am selling them because I don't anticipate needing them in the future. Some colors have only been tested, and some are unused. You can use them for various purposes, such as writing the fillings of rice balls or drawing pictures of flowers. How about using them for your children's lunches? For those who understand that these are used items, thank you for your consideration.
