Width: 20mm x 100cm Material: Polyester Sold in 100cm cuts. *Shipped via mini-letter, for postal delivery. Iron-on tape for repairing clothing. Easy for beginners! Allows for quick and simple repairs, preventing water penetration and lasting longer than before. For areas where the clothing fabric is thin, applying the tape in two layers is even more effective. Are your elbows and knees worn out? It's a waste to have to buy new clothes just because of a small tear! Extend the life of your clothes by one season! Holes tend to get bigger, so we recommend repairing them as soon as you find them, even if they're just a few centimeters! Here are some frequently asked questions: Question: Is it waterproof? Answer: We recommend using the tape primarily for reinforcing waterproof seams. Fabrics vary, so the tape may not completely seal all holes depending on the fabric. It's best to repair the hole itself with a strong waterproof bond and then apply the tape on top for reinforcement to further prevent water penetration. Using clothing-specific bond will further enhance waterproofing. Of course, the tape is effective on its own. Personally, I used it to prevent water from seeping in through frayed seams. I also used it on torn jersey sections. To be precise, it doesn't guarantee complete waterproofing, but it significantly improves durability. This is just my personal opinion, so please take it as a reference. Question: Are there different types of Melco tape? Answer: When making clothing, stretchability is important because you use it in lengths of tens of centimeters, but for repairs, the goal is to fix holes and frays of a few centimeters, so this tape will work fine. It might be easier to think of Melco tape for making clothes and Melco tape for repairs as separate things. Above all, if you're asking if repair tape can last a lifetime, the answer is no, and there will be areas that can't be fixed with tape. That's when it's time to replace the garment, so if you use the tape, you can expect it to last for an average of one season or longer, and you won't have to worry too much. It's definitely better than doing nothing!
