Thai Nalan Foot Sticker is a scam. Just find a brand, preferably foreign. If you can't find the best one, you won't know for yourself. Then find a black workshop to produce the cheapest inferior products, label them as imported goods and sell them at a high price to deceive people. This scam has long existed. Don't be fooled easily. Where will you look if something goes wrong with the product? Thailand? Nobody cares. Health is still very important. Be careful.
