This is an ebonite grip for the Graph 1000. (Blue x Black Marble) It's hard to see in the image, but there's a slight marble pattern. The marble pattern is faint. The image shows a 0.5mm, but it supports all lead diameters: 0.3, 0.4, 0.5, 0.7, and 0.9. The custom grip in the image is a sample. While there are slight differences in the marble patterns, we exclude any individual pieces where the marble pattern is not aesthetically pleasing, so please purchase with confidence. ● Please refrain from price negotiations. ● Please purchase with the understanding that this is a handmade item. ● Due to limited material availability, this is a limited quantity item. ● To prevent product exchanges or issues, we do not accept returns or refunds. Thank you for your understanding. ● Colored marble ebonite material is very rare and difficult to process, so there is a limit to the number we can produce. Please understand.
