I bought these medium vacuum bags from Amazon Japan. I did a prime free trial for free shipping and did a pick up at familymart. It helped to double the capacity of my suitcase. I also saw something similar later at Daiso that were roll up. Not sure if the roll up would work as well as this one with the handheld pump. One of my hotels did have a service for vacuum sealing that was 300jpy but once sealed you couldn’t reopen. I liked with these from Amazon I could open again.
Hope this helps 🙂
