Review on JavaFlex (Pastel Swirl) Reusable Shatterproof Foldable Silicone Pour Over Coffee Maker And Storage Pouch by Erica Nelson

I love that it's made of flexible, unbreakable silicone! It has two holes to prevent steam from being sucked into the mug. The problem I have with this particular design is that the bottom hole is round instead of oval. Cone filters do not fit properly in this form. Sitting incorrectly sometimes causes the cup to appear thick. The filter will not stick to the pulp of this coffee bag and if you try to get it to fit you will unravel the filter stitching and potentially end up in your mug. I'm gonna make a mess The creek splits in two with a design instead of flowing straight down. All in all, it's great for travel, if you're on a hike, or anywhere else where you don't mind spilled coffee or a possible drip in the cup.
