For investors in kind who primarily want medium edged bars in stock in order to have a high degree of flexibility in further processing, the Bar Box is a good choice. It contains as many medium edged Osmium bars as possible, depending on the weight of the individual bars, and is then replenished with squares up to the total tendered value. All products are intended to be sold to investors or into the jewellery market for further processing after the investment period. All possible shapes can be cut from the rectangular bars using the wire erosion process. The standardisation of the contained products facilitates resale. All Osmium bars are certified. The authenticity is accepted on the basis of this certification when resold by jewellers without further chemical or physical tests. To adjust the quantity of goods to the price, a little more Osmium is delivered free of charge in addition to the oversupply. For the replenishment with Osmium squares, the general rule is that for these few objects to reach the target sum, the cutting surcharge is included in the price of the squares. The effect on the total price is small, but we would like to draw attention to it, as the total amount of Osmium thus decreases slightly when the box is replenished to a fixed price.
