I am selling this item because I accidentally purchased multiple. This is a new, unopened product. The photos are from when I opened my own product. The following is a quote: OREA's most compact and tough "OREA O1 Brewer “BABY O”" From the Brewers Cup to the summit, experience the best coffee experience in any situation. Product Details Small but powerful The OREA O1 Brewer (commonly known as BABY O) is a compact, all-in-one flat-bottom dripper that achieves the ideal single-cup extraction, combining stable extraction, portability, and high versatility. OREA's original "open bottom design," which is a characteristic of OREA drippers, has been used in glass, porcelain, and V4 plastic products. By providing a ridge (inner step), the filter can be firmly supported. In addition, an air layer is created between the filter and the dripper, realizing an ideal balance of structure. The filter is curved in a shape that allows hot water to gather in the center and fits the dripper. This creates a flow of water similar to a cone, even with a shallow flat bottom, allowing for extraction with candy-like acidity without compromising balance, sweetness, or body. Why a small dripper now? Small drippers allow you to bring the kettle spout closer, allowing for finer control of the water flow, making them exceptionally easy to use for single-dose extraction. In recent years, with the popularity of hyper-specialty coffee, small-batch extractions of 8g, 10g, and 12g have become increasingly popular. Also, compact and lightweight drippers are attracting attention for travel and outdoor scenes, and the tough and easy-to-handle material, tritan resin, is also popular.
