Make the spout on the spot! I found a slightly unusual measuring cup, so I will introduce it.
A silicon measuring cup named "ViV Silicone Measuring Cup". A part of the side surface is designed to be thin, and it will shrink when force is applied from the left and right. This squeezed part serves as a spout.
When I actually used it, I felt it was easy to pour because the width of the spout could be changed freely. Since the sides are uneven, it is also excellent in stability when holding.
"ViV Silicon Measure Cup" comes in three sizes: 100cc, 250cc and 500cc. It is sold on various mail-order sites, and the price range is around 800 to 1,500 yen. There are 3 types of color variations (clear, red, green), so why not choose your favorite size and color combination and use it?
