Review: Great quality and good value for money - Great quality and good value for money - Used these to patch denim jeans knees in my work trousers - easy to apply with a hot Iron and easy to match with the various colours of patches supplied - Stays in place well after applying - good stick when ironed on - Jeans have been washed several time since fitting with no problems
Review: Decent patches - These jean patches are pretty good for repairing minor damage to jeans. They are easy enough to use with the iron on method and adhesion is reliable, though they will stick better to smoother areas of the jeans. They didn't work well to fix some holes that appeared around the crotch unfortunately! but for patching over holes on the legs they were good and you can cut them down to the size you need. They blend in quite well - there is a decent mix of shades in here though so you should be able to find a close match for your own needs. I'd say these are good value for the price as they're decent quality and are a reliable and fairly quick fix.

## 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. 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: Can you use these to reenforce the crotch of jeans before a hole appears?**
A: Yes any where on your jeans.
And it is a iron on patch.

**Q: If you use these on the inside of the jeans, doesn’t it end up with sticky stuff showing through the hole?**
A: I used them on the inside of a pair of levis to mend a rip so not really a hole but no problem at all. Don’t leave the iron pressure on too long. 60 seconds only.

**Q: Can you iron these on the inside?**
A: Yes, I ironed them on the inside of a pair of jeans. Can hardly tell there’s a patch there at all

**Q: The hole is quite open and I wondered when I iron it on the front will the adhesive patch stick ok as material is missing. Hope that makes sense.**
A: Yes, it will work, I used them for this too. You can either iron the patch over the hole from the outside (so all you see s a patch) or from the inside (so you see a hole with a patch behind it) (which is what I did)

### ⭐⭐⭐⭐⭐ Excellent Iron-on Patches – Strong, Durable, and Easy to Use!
*by C***. on 3 March 2025*

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.
