Pencil Refill 5.6 mm

Refills for pencils with a lead of 5.6 mm. The Kaweco box contains 3 leads in gradation 5B and fits the Kaweco Sketch Up Pencil perfectly, while the Koh-I-Noor boxes contain each 6 refills in gradation 6B. They are a bit longer, which makes it necessary to cut them before using them in the Sketch Up, but that´s easy.
