Last year, I purchased three boxes through mail order. I used one box and stored the other two unused. I'm now using a different supplement, so I'm putting these up for sale as it's a waste. The expiration date is May 2026, so the remaining time is not long, but you should be able to use them without any problems if you take them daily. Each box contains 45 tablets, and the recommended dosage is 1-3 tablets per day. For those concerned about their health during the New Year holidays... Thank you. Reference price: About 10,000 yen for three boxes.
