Nut allergies, wheat intolerance or dairy allergy, does anyone in your household suffer from one of these? Whatever allergies family members have you need to make sure their health isn't put at risk. Why not colour code your food items so you can see what is suitable for them to eat as soon as you open the cupboard? These round labels are great for colour coding as they come in a range of different colours. This is just one way that these blue labels can be used around the home. You can also use them for home filing or marking storage items so they are instantly recognisable.
