Shipping Vinyl Bags with Tape - 100 Sheets Specifications: A4 (Size to fit comfortably) Size: 250 x 340 + 40mm Material: LDPE Thickness: 0.06mm (60 microns) Color: White These are double-layered bags with a focus on cost performance. Each bag weighs approximately 10g. Since the postage for regular mail changes depending on the weight, I use these because I want to use materials that are as light and durable as possible♪ Suitable size for Yu-Packet Post and non-standard size regular mail! You can also use them for Nekopos by folding the edges(^^) I myself struggled a lot with which shipping vinyl bags to choose (><) It seems that those that are too cheap have quality issues, but I want to keep costs down as much as possible to sell and ship at a lower price... In the end, I chose these double-layered bags♪ I think they are probably manufactured overseas, but they are products that a domestic company sells with great confidence in their quality and service, so I bought a case from the first time (lol) I am very satisfied with the quality and ease of use! I plan to fold them and ship them via Click Post.
