Sea to Summit Coffee Dripper X BREW Used about 3 times. It's clean as I washed it thoroughly after each use. Personally, I find it a little difficult to fold. Please check the condition in the images. [Foldable Design] It folds up compactly, making it easy to carry and perfect for outdoor activities and travel. It fits perfectly in the X-Cup from the same manufacturer. [Reusable Mesh Filter] No need for disposable filters, making it an environmentally friendly choice. It maximizes the flavor of your coffee. [BPA-Free Material] Made with BPA-free silicone material for safety, so you can use it with peace of mind. - Brand: Sea to Summit - Model Name: X BREW - Capacity: 480ml - Material: Silicone - Features: Foldable, reusable mesh filter - BPA Free: Yes - Filter-Free: Yes I think this is a rare item that is now difficult to obtain.
