## Features

- 𝗣𝗮𝗰𝗸𝗮𝗴𝗲 𝗜𝗻𝗰𝗹𝘂𝗱𝗲𝘀: 12 iron-on denim patches, size 3" by 4-1/4" (7.5 cm x 10.5 cm). Ideal size will help to conceal the shortcomings of both small and large holes and enough to create your own design. Four different shades of blue will perfectly match your different denim clothes. Front side of the patches is 100% cotton, rear side is covered with the strongest hot-melt adhesive film. Patches made in EU using high quality materials.
- 𝗘𝗮𝘀𝘆 𝘁𝗼 𝗔𝗽𝗽𝗹𝘆: It will take only a few minutes to repair or decorate your jeans, as only an iron is required. Preheat your iron to the maximum, then place the patch on the desired spot and iron over the patch with pressure for 60 seconds. You don’t have to sew patch on or use further fabric glue, hot-melt adhesive film on each patch is very durable by itself. CAUTION: Do not apply patches using hair straighteners or other heating objects, only use an iron.
- 𝗢𝘂𝘁𝘀𝗶𝗱𝗲 & 𝗜𝗻𝘀𝗶𝗱𝗲 𝗦𝘂𝗶𝘁𝗮𝗯𝗶𝗹𝗶𝘁𝘆: You can place the patches on the outside of a garment. Use scissors or die-cut machine to cut the patches to the size or shape you want; package includes several templates to help you decorate your favorite clothes. You can also apply patches from the inside of a garment, this way the shiny rear side of the patch shows through the hole. After a couple of washes, the shiny glue will disappear and it will look like normal fabric.
- 𝗠𝗮𝗰𝗵𝗶𝗻𝗲 𝗪𝗮𝘀𝗵𝗮𝗯𝗹𝗲: Applied patches are washable at high temperature; they can also be tumble dried on a high temperature setting. Even if applied patch starts to peel off after some time, simply re-iron the patch again. One patch can be re-ironed at least 3 times, even after washing. To prevent the felting off and curling up, pay special attention to the corners, butt areas and seams when applying the patches.
- 𝗠𝗼𝗻𝗲𝘆 𝗦𝗮𝘃𝗲𝗿: Repair crotch areas, knees, elbows, pockets etc. when it already has tears marks, or use the patches to prevent future problems. Place a patch inside of the garment on a weak spot before the problem transpires, prolong the life of your new clothes. Not only pants and jackets can be fixed, but also sheets, car seats, even socks and many more. Carefully read the instructions of the fabric which you are going to repair, it has to withstand the highest temperature of an iron.

## Questions & Answers

**Q: If ironed on the inside, can you see the glue on the outside, does it seep through?**
A: My jeans had split out in the rear by a pocket.  So the split was vertical and approx 4 inches long..  I ironed the patch from the inside keeping the split closed up tightly on the outside....  Need to be part octopus but it worked... Very happy with a 15 minute fix for someone who would never attempt to use a sewing machine.... Cannot see the patch from the outside.......... and no glue seeped through..
Very happy

**Q: I want to iron these on under a hole so it will show through. but won't it be shiny? and glue looking? the hole is big. thanks**
A: Yes, I think it would be shiny. You would probably have to put a piece of matching material over the sticky shiny part of the patch. I would think it would be hard to iron on a patch over a big hole without some fabric for it to stick to.

**Q: Would this patch fix ripped back pockets from the inside of back pocket?**
A: I don't see why not. I have used them on the inside to prevent wear through from my prosthetic device.

**Q: Do you need fabric glue to apply the patch on?**
A: No, patch already has glue, the hot iron melts the glue

These ZEFFFKA denim iron-on patches are absolutely fantastic! Whether you’re repairing worn-out jeans, reinforcing weak spots, or getting creative with custom designs, this kit has you covered. The strong adhesive makes them incredibly secure—once ironed on properly, they stay put even after multiple washes. The 100% cotton material blends seamlessly with denim and other fabrics, making repairs almost unnoticeable. I love the assorted blue shades, which match different jeans perfectly. What’s even better is that they can be used inside or outside of garments, making them versatile for repairs and reinforcement. They work on jeans, jackets, workwear, and even non-denim fabrics. If you need reliable, easy-to-apply patches that actually last, this is the best set out there.
