Thank you for viewing. While YKK AquaGuard zippers (water-resistant type) are used, they are not inherently completely waterproof due to their structure. Therefore, to prioritize durability, we opted for sewing instead of relying solely on bonding with adhesive for waterproofing, as the latter could potentially peel. Furthermore, we reinforce the seams by applying seam tape to the back side, covering the seam allowances. 【Size (approx.)】 Width: 30cm x Depth: 16.5cm x Height: 9.6cm Weight: Approximately 18g Materials: 3-CT2E08 “Composite Fabric” x YKK AquaGuard Zipper Zipper Color: Gray Cord: Reflective ⸻ 【Materials】 • DCF 3-CT2E08 (approx. 0.8oz) is used. • Due to the nature of the material, streaks and wrinkles may appear in areas where the coating resin overlaps. → This is not a defect, but rather a unique characteristic of DCF. It will soften with use and develop a richer texture. 【Sewing】 • Sewing is done with an industrial sewing machine, with a stitch width of approximately 3.6mm and a seam allowance of approximately 5mm. → Because DCF material is susceptible to pinholes, the spacing between the holes was made slightly wider. • Seam tape is applied to the back side, covering the seam allowances, to ensure water resistance and strength. (The seam allowances are folded towards the bottom.) → Since the seam tape is applied by hand, the application may be slightly uneven in some areas. This does not affect the use of the product, but please be aware of this if you are looking for the precision of a commercially manufactured item or are particularly detail-oriented. Please refer to the photos for details. Feel free to comment if you have any questions. The DCF material used is only enough to produce 30 items. The product will be discontinued when the stock runs out, so please consider purchasing if you are interested. ⸻
