Bought this earlier this week and arrived a lot quicker than expected in 2 days!! Does exactly what it says on the tin, which is a piping bag. What more do you want? Another plus point is the fact that it only costs less than 20p for each piping bag which is super cheap compared to others! I never fancy the idea of re-using my piping bag because it's simply impossible to wash them properly and get all the grease out for next use. Thus a cheap disposable piping bag that works perfectly like this product is ideal. Simply tear it from the roll, do the piping and chuck it in the bin. The size of this piping bag is also ideal for macarons because they tend to be made in moderate-large batches and the design is super easy to get to grips with. All in all, I'm very well pleased with this product and in fact I have just placed another order even though I still have more than half left! 5 stars. Defo.
P/S: I only used these bags for piping macaron batter and the filling, I don't think you can fit a fancy shaped nozzle at the tip so they're probably not as useful if you wish to pipe up some fancy cake decorations.
