Solid black granite. Overall size: 23 x 10cm. Images will be laser etched in black and white as shown in the product image. Delivery 5-7 days.UPLOADING YOUR OWN IMAGE If you are uploading your own image, please ensure it is of good quality as poor quality images result in poor quality engraving. For best results, upload a 300dpi image with a file size of over 1mb. Please avoid low-resolution images of less than 200k. Images that are too dark or “blown out” will not engrave and you will be disappointed with the results. As a rule of thumb, if the image is tiny, grainy or has bits missing, it will probably be unsuitable.
