- The seven-segment magnetic structure and the limited position structure can effectively prevent disintegration.
- One thing to note is that the author's seven-segment structure has six magnets on one side and seven magnets on the other side. Some customers and we have feedback that they want a magnet to be included with the package, and it is up to the customer to choose whether to install the magnet. So all future donut packages will come with four corresponding magnets.
