These are 3mm diameter round rods made of hard, easy-to-work South Sea lumber. Ideal for filling screw holes in pickguards, etc. The length is specified as 15cm, but due to hand-cutting, the lengths will vary. (We cut them so they are no shorter than 15cm, so please consider them to be slightly less than 15cm.) Each rod has been coated with beeswax, making them less susceptible to humidity. They will be shipped in an envelope. Discounts are not available for this product. Also, except for questions, we will omit greetings after purchase and shipping completion notifications. Thank you for your understanding.
