[CHAT] Has anyone else used these? Are they worth the big bucks?

I've been using the standard DMC bobbins and writing on them with a fine point Sharpie but I'm always worried about that colouring off on the thread. And it does wear off over time with handling. I've tried some of the custom bobbins that allow you to put the plastic casing with the number right onto it but so many of them are drop bobbins and or they just don't store neatly. These seem like a great option for people who have a lot of bobbins to keep organized but is it truly worth the high price? Would love to know if anyone has bought them!

Update: I have tried a label maker but have been unsuccessful. They either don’t print small enough for the four digit numbers or the stickers aren’t sticky enough or both.
