- Refills 5.6 mm in 2B and 5B
- Fitting the Sketch Up Pencil and the Metal Pencil Holder
Refills for pencils with a lead of 5.6 mm. The Kaweco box contains 3 leads in gradation 5B and fits the Sketch Up perfectly, while the Koh-I-Noor box contains 6 refills in gradation 2B, fitting the Metal Pencil Holder. But you also swap it and use them the other way round – the Koh-I-Noor are a bit longer, which makes it necessary to cut them before using them in the Sketch Up. But that’s easy. Please find here the Sketch Up Pencil and the Metal Pencil Holder.
