One lot of 40 glass filter bowls made by high-grade part number gs100. Most of these have a cork filter in them every box that I open except for a few did. The cork filter is rather fragile and would probably be okay if you soak it in gas or oil first but basically they are fragile. These way quite a bit so I will ship them in a large flat rate box surrounded by styrofoam. There are two layers in the Box in the picture. These are nice thick glass and in excellent shape with the indent on the top to accept the bail nut.
