Thank you for viewing! This is a beer foam maker! I bought this a while ago, but I've only used it a few times and have been storing it. It's battery-operated and creates creamy foam, making your beer taste delicious(^^) You set the can, pour normally at first, and then press the button at the end to create the foam. I don't drink much alcohol these days, so I'm selling it. Please note that there are no instructions or box. ★ Depending on the size of the item, I may change the shipping method between Yu-Yu Mercari and Raku-Raku Mercari. ★ I am also selling on other sites, so I may delete the listing without notice even if you have liked it. ★ I will prioritize the person who purchases first, even if there are comments. ★ Please consider this item with the understanding that it is stored at home. ★ I am selling various items while decluttering my home, so please take a look(^^) ★ When shipping, I will recycle materials from my home, so please understand. I hope to sell it to someone who needs it, so please consider purchasing it(^^)
