Review on 6 PCS Nicpro Art Mechanical Pencils Set With 4B 2B HB 2H Graphite Lead Refills, 0.3/0.5/0.7/0.9Mm Artist Drafting Pencil And 2PCS 2Mm Lead Holder For Writing Sketching Drawing With Eraser Case. by Jabari Campbell

Nos 2.0, 0.3, and the 0.3 work perfectly. But there is a big problem with the 0.5 and 0.7.I have been working with the 4 pencils continuously and they have never failed me.A few days ago I decided to use the 5 and the 7. To my utter disappointment neither would the lead come nor would they load.I tried to use lead from other reputable manufacturers thinking perhaps the leads they came with were the wrong gauge. Same result. There must be something radically wrong with them.I know it has been two years since I bought the set, but as I primarily use the 3 and 9, I hadn’t been using the 5 and 7 until very recently.I am reaching out to either Ebay or the supplier to send me replacements for the faulty ones, namely the 0.5 and the 0.7.Once I receive the replacements I will update my review. Thanks
