This product is a custom-made bag for the Evernew 400FD, using Dyneema®︎ Composite Fabric DCF (formerly Cuben Fiber) with a printed design. 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. The flashy pattern is incredibly unique and cute. Since there's no other pattern exactly like it, please consider purchasing if it catches your eye. The larger size OD can (250) also fits in it, which can help prevent rust inside your cooker. It's a good size and convenient to have one. I can't make many, so please consider purchasing early if you're interested.
