I purchased three new life preservers six years ago for boat inspections, but since we always go out with two people, the third one has been stored in the closet unused. I kept it to maintain the boat inspection for a three-person boat. As shown in the eighth photo, the same product is currently sold on major Am⚪︎⚪︎⚪︎n. For boat inspections, the gas expiration date is not a concern, so you can inflate it by mouth and have it checked, which is acceptable. Of course, it has the Sakura mark and JCI certification. I don't think you'll find this price for a new, unused item. Chinese-made products without the Sakura mark are sold for 4,000 to 5,000 yen, but those without the Sakura mark won't pass inspection. If you get a spot check, you're out! You'll get a fine. You could buy a lot of life jackets with the fine money (lol). I am currently using the life jacket I bought at the same time. However, last year, the moment I sprayed it with the shower to clean it in the bathroom, it went "BOOM" and inflated with air, which surprised me. But it means it works properly. I paid about 3,000 yen to replace the cylinder in this everyday life jacket (lol). Of course, this life jacket also passed the boat inspection last fall. I am selling this one at a bargain price because I am changing my boat from a three-person boat to a two-person boat. Those who know the ropes will see this as a great deal.
