Product Description:
   A high-end, elegant, and high-grade push-resistant cup – the Taishan Vacuum Cup, is now available. The Taishan Vacuum Cup, in addition to possessing the function of staying upright after being set down, also inherits the high-end and mature style to develop the new generation of 'unyielding cups'.
The Taishan vacuum cup also has a unique function: it remains upright when pushed from above (on a flat surface), whether it's pushed front, back, left, or right, or if the supporting surface beneath moves. It can be easily lifted vertically (avoiding lifting at an angle), allowing it to emerge effortlessly. When the cup is placed on a flat surface, it won't topple over if pushed from any direction, nor will it fall if the supporting base beneath moves. This eliminates the inconvenience of accidentally knocking over the cup on a desk, causing wet documents or scalding someone; the risk of a child knocking it over and scalding themselves; or the discomfort of the cup spilling when the train shakes during a journey. It makes daily activities a little less frustrating and adds more joy and comfort. Of course, you need to avoid lifting the cup at an angle, or it might cling to the table and refuse to let go!
