What is 'Serafil' mentioned in the description?
One would expect bag descriptions to talk about the outer material or leather, but an unfamiliar name is written alongside the sewing, leaving one stuck on what it refers to.
Serafil is not a fabric or leather, but the name of the sewing thread used to stitch the bag, and this belt bag was sewn with that German thread.
In bag descriptions, the place where a name appears is usually the outer material. However, for Libro Belt Bag in Red, instead of stating what the exterior is made of, it indicates what it was sewn with — noting that the sewing was finished with thread from Germany's Serafil[1].
There is a reason to mention the thread separately. The moment items are put into a bag, the weight concentrates on the seams where the bottom and straps attach, and what actually withstands that force is not the fabric, but the thread running between it. Therefore, there are cases where the thread breaks first and makes the bag unusable even though the outer material remains fine. For stitching that bears load, such as in bags or shoes, it is common to use polyester-based thread made to withstand tension and friction, and to manage thickness by specifying the count. This means that sewing threads, just like outer materials, are divided by the manufacturing company and grade.
hmmm, no matter how closely one inspects the finished bag, the thread is a part whose manufacturer cannot be identified, so there is virtually no way to verify it when purchasing unless it is stated in the description.
