This is a "made-to-order product" that can be customized to your specifications, including the color (white or black), screw size, LH2 (distance from the bottom to the screw receiver), as well as the overall length, maximum diameter, and dimensions of the tapered section. After winning the bid (entering the purchase), please inform us of your desired specifications (color, screw size, dimensions, etc.) in the message section. We will begin production after confirming your payment. We will ship the product immediately after completion, but please note that delivery usually takes about 1-2 weeks. The material POM (polyacetal) is a resin also known as "Duracon" (trade name), which is excellent in mechanical strength and sliding performance. It is used in parts that require hygiene, such as gears, bearings, food processing machinery, and medical equipment parts. It is also resistant to heat and does not get so hot that you cannot touch it in the summer. The specific gravity is 1.41, so it is considerably heavier than wood. <<Specifications that can be specified>> 1. Material color (white or black) 2.
