Flat-Bottom Rinse Assist Tool "1021" for Wave Drippers 『Domestic Genuine Product』 Coffee Filter Paper High-Performance Resin Tritan Flat Bottom Wave Filter OREA, Kalita Wave Dripper, F70 Flat Bottom, B75, SIMPLIFY the Brewer, etc. (Copied from Amazon) This tool is used when rinsing the paper before brewing drip coffee or pour-over. Simply set the paper filter as usual, place the tool on top, and pour hot water. This allows the paper filter to be neatly set in the dripper, increasing reproducibility. I usually only use the larger size tool for the amount of coffee I brew, so I am selling this smaller size. I purchased it in March 2025, but I have only used it 5 times. I expect to ship it within 1-2 days of your order, but please understand that this may vary slightly depending on circumstances. I will contact you regarding the estimated shipping time when you place your order. *Please check the size before ordering. It will not fit larger Kalita Wave filters (such as the 185). 【Reference】 ・Amazon price at the time of listing: 3280 yen ・Model: 1021 ・Dimensions: Height 5.5 cm x Width (Top) 6.6 cm x Width (Bottom) 4.2 cm ・Shape: Compatible with flat-bottom drippers ・Raw Material Resin: Tritan ・Heat Resistance: 109℃ ・Included: Main body, domestic genuine product package, bottom lid (transparent, with genuine logo) 【Related】 Drip Coffee Pour Over Paper Filter Paper Assist Rinse Hot Water Rinse
