When choosing from the New Stainless Steel Funnel options, how do XS and S differ in size and use?

5cm and 7cm are the opening diameters of the two funnel options indicated in the official materials^[1]. Regarding these two options to choose from within a single product, the materials tell us three facts^[2][3]. They are the diameter and height dimensions, the weight, and the material of 18-8 stainless steel^[4][5].

The XS specification has a diameter of 5cm, a height of 6cm, and a weight of 26g; being small and light, it is easy to hold by hand and handle when trickling liquid little by little into small seasoning bottles or essential oil bottles with narrow openings^[6]. On the other hand, the S specification has a diameter of 7cm, a height of 7cm, and a weight of 52g; with a wider top, it stably catches liquid when transferring a relatively large amount at once, such as cooking oil or soy sauce^[7].

Both specifications use 18-8 stainless steel, which is resistant to corrosion and odor absorption, so they can be easily cleaned and used hygienically even when they come into contact with oil or acidic seasonings^[8].
