These are the smallest size of T-Sac.
They are perfect for small leaf teas when you are making a single cup or mug. Great for work, travel, or camping, the #1 size is the most compact to carry. For work or when traveling, you can fill the bags before you leave and put a staple through the flap to seal the bag. When camping they can be buried or burned if that is approved at your campground (check with the campground operator to be sure – and if not they are small to carry out).
The #1 size is not a good choice for green tea, or bulky white, oolong, or black teas, as there is not enough interior space for the leaf and the water to mingle.
