Vacplus Futon Compression Bags, Set of 3 ・100 x 80cm Futon Compression Bags, 3 pieces ・Includes dedicated manual pump These futon compression bags were previously sold on Amazon, but it seems they are no longer available. My family likes these futon compression bags, and we still use them with the electric suction pump Q-PON and the dedicated manual pump. I purchased these as spares in June 2021 and have kept them stored in the box. While it's not unheard of for futon compression bags to lose air by the next season, in my case, it happened with about 2 out of 20 bags, which I considered acceptable. I will put the box in a paper bag and ship it via Yu-Yu or Rakuraku Mercari delivery service, size 60-80.
