This is a set of 14 cardboard cores from approximately 30cm and 25cm rolls of plastic wrap. They will be shipped in a paper bag. Great for crafts! * 7 cores are 305mm long x 34mm in diameter (3 of these have a slightly different color) * 5 cores are 305mm long x 30mm in diameter * 2 cores are 250mm long x 30mm in diameter The 34mm diameter cores will have smaller cores inserted inside for shipping, making a total of 14 cores. Please note that measurements are approximate and may have slight variations. I was keeping these for myself, but I have too many now. If you need some in a hurry, please consider these. (This is the last of the 30cm type I have.)
