I had been straining my herbal teas with a small colander, but wanted to infuse them longer increasing the benefits truefold. These are big enough for my herbal tea blends that I make and there is no worry of straining them to find pieces after. I can allow my tea to steep and then just remove the infuser. I like the handle grip and how easy they are to open fill and use. The size, the shape and the handle length are perfect for any size of cup.
