★ This is the pump-type wine preserver, Wine Air-Vac. It can keep opened wine delicious. ★ It was used for about 1 year and then stored in a cupboard. It has been washed and disinfected. I believe it is in clean condition with no noticeable stains, but please check the photos thoroughly. ★ I would appreciate it if you would purchase it with the understanding that it is a used item stored at home. No claims, no returns, please. ★ It will be shipped with waterproofing, likely via Nekoposu or Yu-Packet Post Mini.
