Review on NEPAK 600 Pcs Disposable Tea Filter Bags for Loose Tea, Drawstring Empty Bag for Loose Leaf Tea, with 100% Natural Unbleached Paper (1.97 x 2.76 inch) - Enhance Your Tea Experience with Sustainable Filters! by Kristen Barrett

They are easy to use and consistently good quality. I like that they are unbleached paper. I have purchased several sizes of these tea filters and have found the medium size (6cm x 8cm) to be the most versatile as it allows you to brew almost anything from a cup. a cup of tea in a small teapot - they fit at least a tablespoon of loose tea. The price is great, almost as cheap as buying in bulk, but much more convenient to order through Revain. I make little packets for sale in my tea shop and my customers love them! It is very convenient to put in your purse, desk or locker, and also brew loose tea on the go. 600 pieces should last you a long time.
