These needle cartridges do NOT fit the Dr.pen Ultima M7-W as it states in description. Beware when buying because I noticed when doing the return that they keep $5.00 of your purchase price when you return. I NEVER would have ordered from here had I known that before my purchase! This is pretty ridiculous and VERY POOR business practice if you ask me , especially when their own description states that they will fit the pen I have. BOOOO!
