Kikki.K B6 Black Croco Leather Zippered Planner New and unused - comes w/ B6 undated inserts The zipper is very smooth - rose gold hardware 30 mm rings (You can use Personal Wide inserts in this plannner - though they are slightly smaller than B6 inserts, they do share the same ring distance) - I personally use one with personal wide inserts. Check out my other listings and let me know if you’d like to bundle anything! (I also have Kikki k accessories, Gillio and Van Der Spek planners, and Cloth and Paper and 8Lotus inserts)
