I subscribed to the quarterly subscription. I wasn't sure whether I'd get different items than the monthly subscribers. For anyone with the same question, it turns out you get the regular monthly box for whichever month your quarterly subscription happens to fall on. I subscribed in January, so I got the February box and will presumably get the May box next. My initial impression was that we didn't get much stuff - some black pens, three brush pens and a little notebook. But as I dug in, I realized I was really wrong. The Micron pens are amazing, and I'm really enjoying the huge variety of nibs and the versatility that creates, and with drawing plants the brush pens blend and complement the illustrations very well. It's been pretty meditative to practice drawing succulents and other plants with bold elements and fine detail work and then layer and blend color on top. I'll get a ton of use out of everything in the box and can't wait for May.
