This tea infuser helps to filter the tea from the water in your cup. Just add about 2 teaspoons (or fill half of the metal ball part) with tea, cap and add to boiling hot water. Comes with a base to put the infuser on after it comes out of the water. Don't overfill or the herbs won't have room to expand and water won't be able to get around all the herb to infuse properly. After using, rinse with water and set out to dry.
 
Made of food grade silicone and stainless steel. Comes with three pieces: leaf end, stainless steel ball, & base to put infuser on.
 
Colors: red, orange, yellow, green, blue, purple
 
I will try my best to get you the color you request, but may have to substitute.
