This is a Suwada Seisakusho Ginkgo Nut Cracker and 503 grams of ginkgo nuts harvested this year. There are countless ginkgo nuts. I bought the ginkgo nut cracker in October to eat ginkgo nuts, and I only used it once, but my family doesn't like ginkgo nuts, so I'm putting it up for sale. Besides using them in chawanmushi (savory egg custard) or roasting them as a snack with alcohol, you can also plant them in the ground and the ginkgo tree will sprout. The length of the SUWADA ginkgo nut cracker is 14 cm, and the width of the metal fittings is about 5.3 cm. The width of the metal fittings is adjusted with the attached red hex wrench. - Product Name: Ginkgo Nuts - Tool: Ginkgo Nut Cracker - Material: ABS resin - Manufacturer: Suwada Seisakusho Thank you for looking.
