I was in my LHS yesterday and the guy was trying to sell me a pen. I'm not sure what brand it was but it came in a nice case, had attachments for flowers and regular dabbing. Best thing was they had prefilled carts that had oil in them. They make the oil and sell the carts for $60 per gram. I tried the cart and the oil while there and it was amazing. He said it works better than a Pax for flowers, too. The whole system is $200 (which I think is high) but he will throw in 2 carts and some oil. Then I can buy the prefilled cartridges form him (he's a caregiver). It was the first time I've tried a pen and was very impressed. Since I'd be getting 2 plus grams of oil, it sounds like I should do it. Opinions?
