We carry several sizes of taps and dies dedicated to pen making. If you have a need for a particular size we dont carry contact us and we will see if its possiible to aquire it. A minimum of 12 units is needed to bring the cost into a reasonable price range but we can get single sets.
Postage for overseas shipping is set at a flat rate to cover a variety of countries and different size parcels. I will gladly refund the difference between actual costs and the flat rate amount.
