Cretacolor Graphite Lead, Graphite Lead 4B

Yeah of course! And thank you! Been using a 5.6mm Graphite holder, basically a really thick pencil - I'm not sure if I'm sold on it yet, but it does make shading a bit easier, worth a try. Lead like this: https://www.amazon.com/CRETACOLOR-Artistica-Brevilliers-Charcoal-26001/dp/B0049V47LY/ref=sr_1_46?sr=8-46&th=1 and then you need a holder like this: https://www.amazon.com/Cretacolor-5-6mm-Lead-Holder-Count/dp/B0049V37C4/ref=sr_1_5?crid=1KOZJ9FUXR28Q&sprefix=cretacolor+lead+hold%2Caps%2C155&sr=8-5 probably cheaper ones of those somewheres.
