These 16 oz cobalt blue PET jars are perfect for bulk apothecary items. The square shape makes them easy to hold when pouring scented salts into a hot bath. The wide mouth is ideal for scooping out flavored sugars and herb blends and the deep blue color offers UV protection. The smooth black lid has a pressed foam liner that creates a slight cushion to keep your ingredients fresh. Made in the USA and 100% recyclable in most areas, these jars are a smart choice for your packaging needs.
