ZEFFFKADenim Iron-on Patches Inside & Outside Strongest Glue 100% Cotton Black and White Repair Decorating Kit 12 Pieces Shades of Blue Size 3" by 4-1/4" (7.5 cm x 10.5 cm)

Easy to iron on and they work great.

Ironed on using their instructions. Holds strong. Actually sewed a belt loop into one. It works well.

I've been very pleased with these patches, and I purchased sets in different several colors. Durability is great - I just wish the rest of my barn clothes were this tough. Definitely easy to use (assuming you know how to turn on your iron, of course!), but be ready to lean into the iron with extra pressure, and also make sure you don't scorch your fabric. Adhesion was not perfect but very good; I used some liquid stitch to keep some errant corners down.Overall, I strongly recommend, and I'll purchase again

These Denim replacement patches were just what I needed. Many shades are provided and the instructions on how to apply them were clear. REMEMBER: do NOT use the steam setting on your iron. They have lasted a long time after many different applications, are easy to iron and long great. I don't like torn jeans when I'm working in the garden and down on my hands and knees so these patches provided protection as well as improved appearance.

Update: this is a little late, but I lowered the stars to 3 from a 5. The patches are good quality and color, but they do not stick for very long. They didn't even hold up to two washes before the edges started to loosen, eventually leading to them peeling most of the way off. I ended up sewing the patches in place, they don't look as good that way, but it works to hold them in place.These are the first patches I have ever bought and used, but I am happy with them so far.I had no problems getting these patches to stick, I warmed the jeans for about 30 seconds before placing the patch and following the ironing directions on the package. I tended to iron just under the maximum time they recommend, just to be sure it adhered properly.I haven't tested the hold thoroughly yet, I have worn one pair of jeans for a handful of days doing various activities, and the patches have held. I'm about to toss them in the wash and see how they hold up, if they fail I will update this review. As most people out there that are patching jeans, I have mine patching holes on the inner thigh area. I placed one patch on the outside, and on the opposite leg the patch is on the inside for two reasons: 1, I want to see which patch (inner patch, outer patch) holds up better in terms of wear and tear; 2, having both patches on the outside makes a lovely, loud "swishing" sound when the patches rub together as you walk...I believe I would go with this brand again, should I need more. I would prefer to have a bit more than 3 patches per color, or even be able to choose the specific color you need, as well as having larger patches that you can cut to the size you need. These were almost a tad too small for some of the holes I needed to patch. So be sure to physically measure your project before ordering, to make sure the size works for you!

Quality of these patches is very good. The color selection will match almost any jeans. It was very easy to put on the jeans and looks very nice

Worked well on jeans with iron

I don't know anything about sewing, I saw these and because of the price, I decided to give them a try. These patches are fantastic; they're substantial, and I love the variety of colors available. In an instant, I found one that matched my husband's Dickies jeans. These patches are for THICK FABRIC and were ideal to repair his jeans, which had some rips from construction. The instructions are very clear, all you have to do is follow them as stated and they held up good after washing.
