Number of sets: 35 These are the cores of mt masking tape. The width is 15cm, and the diameter is about 3cm. I have accumulated a lot of them, so I am selling them. How about using them for crafts, handmade projects, or carrying your masking tape around? Masking tape is not included. Some cores may have peeling or stains on the inside. Please refrain from purchasing if you are sensitive to used items. They will be shipped in simple packaging. #yakan'sMaskingTape
