The technology based on titanium is controversial in Japan. Judging from the query results, the group for and against is 5: 5. I have seen the biggest question-and-answer websites in Japan in detail, such as MSN Talk Box and goo. Judging from the information you find in books or magazines, titanium collars have little effect on people's health. So it doesn't hurt to bring it. Many people are worried about the impact on the heart. From a medical point of view, it should not affect the heart.

I have been studying in Japan for five years. Japanese pharmacies really sell a kind of collar called Magne loop. The raw material of this collar is magnesium. It mainly uses magnetic force to play a health care role. The effect is to improve blood circulation, muscle pain and shoulder pain. This brand is sold in many stalls. But most of them are fake textiles from China. The freight on board, excluding the labor cost of Japanese procurement personnel, is 150 yuan. You'd better not believe anything below this price.

There is a Taobao shop called Piger, which is opened by a friend of mine who is studying in Japan. You can find it in the shop search on Taobao's homepage. I can guarantee that every commodity is purchased from a regular Japanese store. Because I often help him buy things. If you are not at ease, we can deliver the goods directly from Japan. Of course, you can also provide a shopping receipt. Commodity prices sometimes change with the exchange rate.
