This strange animal is a replacement filterscreen for the SAN Shatter-proof Plastic Beakers and Stainless Steel french presses (like the Columbia). This special filter has a silicone edge so it won't scratch the interior wall of the SAN Unbreakable beakers or stainless steel press. You can also use it in a glass press to take advantage of it's seal and durability. Note that using this compared to the standard mesh filter will change your cup characteristics a bit. It does a better job of filtering out fine grinds. You can always adjust for this by grinding finer than you normally do. Measures 3.75" wide and 0.37" high.
