Thank you for viewing. This is a very heavy-duty set of a natural stone (granite/granite-like) mortar and pestle. This is a large-capacity, professional-grade model, perfect for making authentic spices and cooking in large quantities. This is a set of a stone mortar, a "khrok hin" (khrok krasa) and pestle (sak), used in Thai cuisine. It is an essential cooking tool for authentic Thai dishes, especially for making papaya salad (som tum) and Thai curry paste. Product Features and Appeal 【Amazing Weight and Stability】 Total weight: Approximately 7.6 kg! (Mortar: approx. 6.6 kg / Pestle: approx. 1.0 kg) Due to this weight, it will not move during cooking, and you can grind ingredients with excellent stability, even hard ones. 【Extra-Large Size, Large Capacity】 With a diameter of 20 cm and a height of 13 cm, you can process a large amount of spices, sesame seeds, herbs, nuts, etc. at once. It is also ideal for making homemade miso, sauces, and pastes. 【Texture of Natural Stone】 The rough surface unique to natural stone firmly grips the ingredients and maximizes the flavor. Size Details Mortar (outer dimensions): Diameter approx. 20 cm / Height approx. 13 cm Pestle (pestle): Length approx. 18 cm Total weight: approx. 7.6 kg Condition and Notes on Use Noticeable scratches: There are fine scratches due to use, but there are no major cracks or chips that affect use. 【Important: About Wobbling】 The bottom is not completely flat, so there may be slight wobbling depending on where it is placed. If you are concerned, you can stabilize it by placing a cloth or silicone mat underneath. Because of the weight, it shouldn't be too much of a problem in actual use, but please understand this before purchasing. Initial treatment: Before use, it is recommended to "remove the astringency" by soaking it in rice washing water to wash away the unique powder of the stone mortar. About Shipping Shipping: Price includes shipping. Packaging: Due to the heavy total weight, each item will be carefully wrapped in cushioning material and shipped with a fragile warning.
