This is a roll of wrap for 50m, so I think the core is quite sturdy. This is for 30cm and 45cm wrap. I'm happy with a profit of 20 yen per roll. This is the core of the wrap used in the kitchen. Calculated at 20 yen per roll, please order from 1 roll. I will use simple packaging. I will either bundle them in a milky white garbage bag or put them in a suitable cardboard box, adjusting the height for shipping. If using a cardboard box, please understand that it will take a little longer. I will go to the supermarket to find them. I would appreciate it if the buyer could look up the shipping costs. I am selling them in sets, so please understand that it may take some time if the stock runs out. In the comments, please specify whether you want 30cm or 45cm, and how many rolls of each? Write the number of rolls and calculate the price. Both are fine, so please write the total number of rolls. Please choose shipping from the post office. I will write about the stock in the comments. Please note that prices will be increased during July and August due to summer vacation. #WrapCore #DIY #Crafts #SummerVacation #Homework Regarding shipping boxes, I have a 100-size box (50x30x18). It can hold up to 45 rolls. For a small number of rolls, I plan to ship them in a garbage bag.
