These are one of the best products in the catalogue. They last for ages although they are a bit fiddly to clean. Leaving to soak full of hot soapy water then using a brush to scour round usually works. They stand while being filled,it's easy to expell air and the seal is leakproof. They can also be squeezed into corners in the freezer. Defrosing in the microwave does not damage them either. Also economical as they are reusable many times.
