When these arrived, I must say I was surprised at how big they were - but that was my fault not correctly reading the size. Having said that and having used them, I am extremely pleased with the quality and the size. I only use them for domestic purposes but they are an excellent size for piping a normal quantity of meringues, icing cupcakes, etc. I've been able to reuse them three times so far and the seams are still holding strong. There's nothing worse than ousing seams and these don't let you down. A quality product delivered in reasonable time.
