I'm a teacher of older students (16+) and use these in the classroom when a student does not have a pen. I hand it to them and ask "what does it say on it?" They read it out and I say "exactly, please give it back at the end."
It's taken 9 months but I've lost 9 of the 10 pens but I know of at least 1 student who has kept it and uses it.
It has started a few conversations like "is that from the Bible?" or "why is God mentioned?" (It shows the needgod.com website) and I can then indicate that I'm a Christian and that it's from the 10 commandments. I've had 1 Sikh return it and say " I'll bring my own pen next time!"
I plan on buying in bulk to give these out to my team, to have to give to students. How amazing, to have non-Christians give out a link to a Christian website!
