This is a giveaway of useful goods I bought too much of. These are long-term storage items from a sewing factory, and the labels may have some discoloration or wrinkles. They are unopened and unused, but please understand this before purchasing and use them for your handmade projects. They will be sent in simple packaging using an inexpensive shipping method. They are stored in a separate room, but there are cats and a smoker. Thank you for your understanding. ~For your reference ※The slit part at the edge may be wrinkled or folded. This is how they are upon arrival. It's the edge part, so it shouldn't affect usage, but please be aware of some wrinkles. Uniform folds: The tape acts as a gauge, allowing you to easily create beautiful folds with consistent widths. Iron-on: Adhere with a medium-heat iron (around 130 degrees Celsius) and wait for it to cool. Uses: Meshwork, bag handles, trimming, finishing edges of clothing. FL is a product developed to improve the efficiency of partial sewing and achieve accurate finishes. It is an adhesive tape used for folding, such as cuffs, pocket openings, pocket reinforcements, belts, front plackets, vents, hem hems, facings, and trimming. Originally used in sewing factories, it can be used in various ways with ingenuity. When making bag handle tapes, neck straps, tabs, etc. with the same fabric, isn't it quite troublesome to fold them to a uniform width? It can also be used for such purposes. It's a great product that speeds up sewing work and allows for beautiful finishes♪ (Use it by heat-sealing with an iron.)
