Durability is time so not sure, does it really matter when a hem is needed? This product hasn't let me down in the past, I love it. Larger sheets cannot be found anymore and THOSE are nice, wish that different sizes were available but this will do.These hemmed 12 curtains in an afternoon. Really enjoyed the ease of use and time savings!Worked great for my curtains but in order for this adhesive to permanently bond cloth you have to be able to use the steam setting on your iron. Some polyester fabrics may not be able to handle that and melt so test the fabric first if you’re concerned. Otherwise this product has been an incredible help, very easy to use and seems long lasting.I’ve never used iron on hem before and it was way easier than I thought with this product. I used it on 2 pairs of jeans about 3 months ago and the hem still looks great after 8-10 washing and drying sessions. Definitely recommend if you want to avoid the cost of a tailor. The tricky part is deciding the length you want!I used this to shorten heavy weight blackout curtains in just minutes. So happy with the results!This was easy to use and effectively held a robe hem.I personally Love this stuff. I’ve had it since my military days… I used it to put patches on my uniforms and they literally never came off!!! You can use it to hem pants too.Tiene buena adhesión, fácil uso, lo aplicas de manera sencilla. Sin embargo, si metes tu prenda a la secadora, desaparece y hay que volver a aplicarlo.No affordable seamstresses to be found so I invested in this item. I used this on some curtains that I bought from Amazon and it seems to be working very well. Hard to say if it will stand the test of time, but per the instructions, if the seams do come apart in the future, you simply reapply heat.Es un producto que te saca de una emergencia, pero no tiene gran durabilidadSirve muy bien para una emergencia, pero a la primera lavada se despega, funciona pero es mejor una bastilla tradicionalBuen producto, tal cual se ofrece en la página. El envío y todo el proceso de compra sin problema y pego perfectamente las cortinas que esperábamos, así que es recomendable para tela gruesa como se menciona en la publicación.
