This listing is for a set of 10 packs of Japanese-made disposable tea filter bags, with 100 bags per pack (1,000 bags total). Each bag measures 9.5 cm × 7 cm and is made from a blend of polyethylene (50%) and polypropylene (50%), materials chosen for their food safety, light weight, and easy folding. The simple fold-over closure keeps all loose contents securely inside without any adhesive or strings needed.

These versatile filter pouches are a staple in Japanese kitchens. Most commonly used for brewing loose-leaf green tea (sencha, hojicha) or black tea directly in a pitcher or cold brew bottle, they eliminate the mess of floating leaves while preserving full flavor. Cold-brew fans will especially appreciate how the bag keeps leaves neatly contained overnight in the fridge — no strainer, no teapot to wash. Just fill, fold, steep, and discard.

Beyond tea, these bags shine as a kitchen multi-tool. Pack them with bonito flakes (katsuobushi) or kombu to make a clean, easy dashi broth for miso soup — simply drop the pouch into the pot and lift it out when done. They also work well for blanching small portions of vegetables at the same time as other ingredients, keeping everything separate without an extra pot. Many customers mention using them daily for dashi, noting it makes homemade soup feel effortless and actually saves money over store-bought stock.

Reviewers consistently praise the low per-unit cost and generous quantity, saying they use them freely without hesitation. Some customers have even found non-kitchen uses, such as sorting small beads or craft supplies by color and size. At 1,000 bags per order, this set is ideal for households that cook Japanese food regularly or anyone looking for a simple, affordable way to brew loose-leaf tea at home.
