Review on ☕ Convenient and Eco-Friendly Tea Filter Bags Set: 300 Disposable Infusers with Free Tea Spoon, Ideal for Loose Leaf Tea, Coffee, Spice, and Herbs by Kimberly Dionne

Take a lighter/match and light one of these bags. What do you see? Does it burn like paper or cotton, or literally melt like every plastic fiber you've ever known? Now look at the two vertical seams. Are they sewn like a natural fiber should be, or can you clearly see that they have been thermally fused/fused with a hot metal press making a triangular pattern into the nylon/polyester/whatever thing? out? Watch the sheen of the fabric surface that never fades or changes. Have you ever seen such a shine on a natural pulp product? I've been using them for years and just realized they're made of synthetic fabric.
