I've found myself shifting planning styles over the past year, and wanted to experiment again with using a print planner and a new layout. I'm really excited about the twinbook. First, the cover is gorgeous and it's a treat using something so nice. Second, I like that I can pick different books, both dated and undated, to meet my needs. I started with the 2026 monthly planner refill and the weekly undated horizontal. It's great so far and I'm glad to know that if my needs change again, I have other options available and can keep using this beautiful cover. Works great with my pens and mildliners too!
Ever struggle with carrying both a planner and a notebook? The twin diaries are compact, everything is in one place and now I have room in my bag. Writing in two different places in two different separate books had been a problem for me but the twin diary solved it all for me! Plus the designs are cute and now I can flip back and forth between notes and a planner..I highly recommend this from Mossery.
Very thoughtful on how it’s designed! I really like the twin notebook so that I don’t need to carry two books everywhere!!!
I love how you can feel how much thought and care went into every aspect of this planner. The cover is gorgeous and feels durable (it was so hard to pick one out of the MANY beautifully illustrated covers), and the paper feels great! I also love the option to refill and customize the contents of a twinbook! That way, I can continue looking at this gorgeous cover <3
I am seriously so thankful for everyone who works at Mossery. I ordered this with something that was out of stock and they worked quickly and diligently to make sure I had a good replacement. They also issued me a refund because there was a discount on the new item I was replacing it with! I still received this cover, just with a full planner refill instead of the twin book. I always love the quality of the stuff Mossery makes. Even the "second chance" items (which I got last year when the planner refills went out of stock so quickly) are great quality! Kind people and great stuff. I will always and forever recommend Mossery for the place to get your planners, notebooks and any other art supplies! The picture is with a transparent sleeve cover (which I've had for 3 years and still holds up!!)
