Two glass jars to prepare and store your baby's meals. The two sizes of 150 mL in pink and 250 mL in blue are complementary and correspond to your baby's first meals. Graduations (in mL and oz) are an effective way to measure formula and see what your baby has eaten. The glass protects the food and won't get damaged over time. The airtight bi-material lid snaps shut and opens with its tab. The 2 glass jars can be placed in the dishwasher, in the microwave and in the freezer, but not in the traditional oven (they resist a maximum temperature of 100°C).
