Been looking for these for a very long time couldn’t find refills for a much loved pen these work perfectly

Simply put - JUNK...*UPDATE -[And as I promised SMTTW]After afew attempts, at contacting SMTTW [Seller/Maker] - And perhaps in response to my 'review' below, they; SMTTW offered up a 'Full Refund' [which I took], regarding my dissatisfaction with their product and service.For me the matter is closed AND no, I will not purchase from them in the future -Don't waste your time /or your MONEY on these 'D1' - multi-pens mini-cartridges from China. I bought mine in March 2022 [now it's April] and needed to re-new my Staedtler 'Retro3' black and red inks.Firstly, these don't fit - The barrel is to narrow [under-sized] and falls out; That is they'll not 'lock-in' and stay secured.Secondly, out of 6 - YES, six cartridges; I finally found one, which wasn't dried out and would write...AND just to see if these cartridges were perhaps not made for a Staedtler multi-pen, I tried them in afew other multi-pens I own -These WILL NOT work in the Skilcraft 'pilot' multi-pen - The 'new' Retro 3 - The rOtring 'quads' or 'trios' - And on one or two other 'older' styled multi-pens, I've had for years; This being the 'shaft' or barrel cartridge is undersized and doesn't securely lock into the pen [and the fact the ink's are poorly made and dried out].Simply put, don't waste your time of these CHEAP cartridges and seek out another manufacturer.It's your money...
