Microscopic observation in general
From Japan

It is a slightly larger cover glass, but in my use it is the best size. It is a case made of paper, but I liked it well thought-out construction.

The goods were promptly sent. It is Matsunami's classic No. 1 cover glass which is necessary for making specimens of the microscope and there are no shortcomings like this at the moment.

For preparation of preparation and train model (HO gauge) for window glass
From Japan

As a cover glass to be used at a high magnification (1000 times or more), it seems to be excellent for fluffstone. I use it for making preparations because of my hobbies, but it does not break, and the glass surface is more uniform than anything, difference will be added from other observation by polarization observation. It seems that it is becoming common sense in the hobby world though it thinks that it will feel a waste to use for the window glass of the model railroad.
