Starting June 2nd (Japan time), we will begin sales of the individual July–December (Book 2) of the avec (Japanese-version only). Previously only on sale as a set, you will now be able to purchase this slim six-month book on its own. (Book 1 will not be sold on its own.)
This is the perfect chance for those getting a late start on a planner, those wanting to try out a new size without committing to an entire book, or those who lost their second half of a previously purchased avec set.
The book will be half the price of the set, so the A6 is 1,188 yen and the A5 is 2,052 yen. It will also include the usual free Hobonichi Store bonuses that come with the Japanese-version books. (More information on bonuses: https://www.1101.com/store/techo/2016/planner/benefit/)
