I mean... What can I say? They are piping bags. They do what they're supposed to. I haven't had one explode yet.They held up and did a good job.Not durable at all. There is no way it can be used cake basing. Every time I try to base a butter cream cake, the tip kept coming pushed out of the end because of the pressure. It is fine if your icing is very thin. But then, with thin icing you can’t base a cake!I use these to fill tartar cups, sour creams & mayo at our restaurant, hold up well.Gets holes in it when the bag is still fullI love that it’s big and thick but apparently not thick enough. When I was trying to pipe a merengue mix it gave out on me. But for regular frostings, it works perfectly fine!Unfortunately they are far thinner than I expected and every single bag has busted so far no matter the consistency of my frosting ....I still use just double them up won't be buying againThe bag is large enough in which I did not have to constantly refill. Very sturdy. I did not rip open at the seams for me at all. Would recommend.
