Price is not negotiable. The photos show the front and back. The front shows larger items, while the back inevitably shows smaller items at the bottom. They range from 1mm to 5mm in size. Regarding the product, all somatid products are handled as miscellaneous goods, so please use them at your own discretion. Somati Plus is also treated as miscellaneous goods, but it activates when 1-2 drops are added together. I personally put it in somatid water and drink it. I will also inform you of my personal usage methods after your purchase. I want you to understand and use it well, so I spent an hour just writing this text. Everyone is very happy with it. I have compiled it in an easy-to-understand manner for first-time users, so please feel free to purchase it. If you understand everything, you can buy it immediately. I also have 100g and 1kg sizes available, so please check them out from the list of items for sale. It will end when the stock runs out.
