This product is a custom-made bag using Dyneema®︎ Composite Fabric DCF (formerly Cuben Fiber) print, designed for the Evernew 400FD. The size is just right, neither too tight nor too loose. When taking out the cup, it's easiest to push it up from the bottom. The fabric thickness is 1.0oz. It has a flashy, unique, and cute pattern. Since there's no other pattern like it, please consider purchasing if it catches your eye. It can also fit a large (250) OD can, which can help prevent rust inside your cooker. It's a good size and convenient to have. I can't make many, so please consider purchasing early if you're interested.
