韩国采购需求：印章和纸胶带,和纸胶带

I'm looking to order 50 rolls of stamp washi tape at 25mm width and 50 rolls of print washi tape at 20mm width, both with a length of 5m. I need more info on the custom logo tube—what options do I have? For both tapes, please confirm the core size (32mm), the washi paper material, and the custom packaging as heat shrink wrap. Could you provide the pricing per roll for both types of washi tape? Also, let me know the next steps to place my order. Thanks!
