Yes, the sachet format is one of the main practical advantages of this product. The box contains 10 individually wrapped sachets, each a single portion, so you do not need to measure loose tea, slice ginger or squeeze lemon. You can keep a few sachets in a desk drawer, a handbag, or a travel bag and prepare a hot drink whenever hot water is available.
Because the tea is instant, the only equipment you need is a cup or mug and a source of hot water. This makes it useful in the office between meetings, during travel, or on a cold morning at home. The individual wrapping helps protect the granules from moisture and keeps them dry until use.
For storage, keep the sachets in a dry place away from direct sunlight and strong odours. Once a sachet is opened, use the contents immediately, because the granules are meant to dissolve in water and may absorb moisture from the air. Do not store an opened sachet for later.
If you are travelling, remember that you will need access to hot water, so check whether your accommodation or transport provides it. The tea itself is a flavoured instant beverage and is not a substitute for a balanced diet.
