"Top and bottom fits nicely."
"I was initially concerned if there would be much of a vacuum leak at the section where the two parts of the funnel snap together. I found when using this with a 1 liter filter flask that it was more practical to wrap a section of the spigot of the funnel in self-fusing rubber tape to build up a stopper to fit the flask than to try to bore out a large enough hole in a rubber stopper."
"Only drawback to this size is the neck is almost as large as my flask so I had to improvise with some amalgamated tape to get a good seal for vacuum."
"Is not exactly a quality product I would have "faith" in this product performing as you would hope, in a lab environment with expensive equipment and chemicals... Time to do a little better research."
"It's plastic it comes in two Pieces will not work for what I need it for ~no plastic ~doesn't seal well."
"Actually it is clear that this is designed for 125mm paper, with 130mm outer diameter, and 5mm of thickness. Something went wrong with post fabrication plastic shrinkage for sure that it couldn't be rated for 125mm, and thus these guys are selling as compatible for 110mm paper."
Fixed and removable filter plates are 6.4mm (1/4”) thick high density polyethylene with a non-porous circumference to better fasten. Fixed or removable porous filter plate supported by a multiple ring grid.

I happened to have a decorative ceramic pot on my counter that the funnel drops into with about a half inch sticking up for safety and easy grabbing, and because it is glass, it is barely noticeable so it does not mess with my decor."
