B4 size delivery vinyl bags! When A4 is a little too small, but you need it to fit in the post... this size is convenient! *This size itself does not fit in the post. Please measure and confirm before posting. 80 microns thick! You'll understand the thickness just by touching it. Safe for the rainy and winter seasons! Why not give it a try? Multiple sets are also available! Perfect for sellers, of course, but also great for small gifts or gift exchanges, as you can hand them over without revealing the contents! Water-resistant, making it convenient for posting in the mail ★ Brand new, unused, but will be packaged from a bag of 100. Will be folded for shipping, and may have creases upon arrival m(_ _)m Thank you for your understanding. I sometimes use these for water protection for 60-size boxes! I use them with confidence even over the box! *This is a personal opinion. #realiser Delivery vinyl bag B4 Pink
