The Joseph Joseph Nest Prep and Store Bowl Set is made from high quality 18/8 stainless steel, meaning the bowls won't stain or retain odours. Each stainless-steel bowl in this 4-piece set has its own silicone lid so you can easily prepare food in advance and then store it until needed. Bowls nest inside each other for space-saving storage and have non-slip bases. Bowl sizes: 5L (169 oz), 3.8L (128 oz), 2.1L (71 oz) and 1.2L (40 oz)
