Yep, those are the pens I had seen on Amazon over a year ago, but they were “unavailable”. As far as my other brush pens, they won’t stay in. I clamp them, but they easily come straight up out of the housing. Hopefully one day, they’ll make the pens available in the US. I requested them when I first got my machine, so when I saw them pop up on Amazon I was so excited, but then was let down with “unavailable” 
. I’ll try purchasing the adapters, and yes, if they don’t work, I’ll send them back.
I had a look through the topics you shared. They seem to have the same problem I have. It’s ok. I can always just hand draw stuff. I saw that you can PTC with your Crafter, though? Mine has never worked for that. I can print, but it doesn’t cut, at all. It won’t even make cuts when I do the calibration sheet. I tried creating an offset around my artwork, but the cut was off. I’m going to try some of the tips you shared in that thread, and see if it works for me. If not, oh well, I’m planning on buying the iCraft this Christmas so I can PTC my artwork for stickers. That was the main reason I bought the Crafter lol. Thanks so much for your help.
