I have these exact some pens and they just can’t be twisted to open. The pens I got had refills in the pack, and they look the same as the ones in this video. I have tried to twist them, but they don’t budge. Having red the comments here, looks like they are way tighter than this video suggests so though the pens can be opened it is not as straightforward as the video since many people here seem to have used something additional as a grip to twist this open. I have found that the retractable ones are way easier to open, which is how it should be. The ones shown in this video cannot be opened easily at all. I got more help from reading the comments here than seeing the misleading video.
This was an awesome in-depth tutorial. A lot of the resources I've found don't go into detail on some of the techniques you mention about strokes ("ending the stroke going in, not out"), but you go through this very clearly. Thanks so much!
Nice.😢 All the letters I write to people from our home in Hawai'i totally disappeared by the time the recipients opened them. I wish I had known this years ago. People were embarrassed for me 🤦🏻♀️🤦🏻♀️🤦🏻♀️
It also disappears from extreme heat and cold. I left paperwork in my car that I know I filled out. The next day after leaving it in below freezing temps, it was gone!! Nothing like a pen testing out how crazy I think I am!
Adding on to the previous comments, yes it can be pretty tight and challenging to come off... However i found just grabbing a cloth in your left hand to remove friction and getting a firm grip while trying to twist with your right hand seems to get the job done. It's my second time refilling and it's a pain every time, but at least it works for now.
