These pretty glass jars for herbs and spices, save on plastic waste (you can buy in bulk with reusable tubs from zero waste shops, then decant). They keep your ingredients dry and flavourful, and the bamboo lids keep them secure, so they don’t lose taste.
Keep herbs and spices away from young children and pets (nutmeg/mace and citrus herbs are toxic to pets). Read more on food safety for people & pets.
Jars with tight lids stop air and moisture from sneaking in, and also these jars are inert, so won’t affect the taste, unlike plastic.
