To be honest kimono is worth 2500 or maybe 2000 cause u get about 700 BP and for sure if its in the lucky board will be more than 50 coupon a frag...now yes u get other stuff but there are also refines and charms there so getting them and upgrading ur account benefits more than a kimono in a long run. But to be fair I think summer youth sai will be again in there...

Well than u go for charms and if the kimono or other thing that you want is not in there you dont spend much on the lucky board...simple cause I need 70 medium refines to finish with them also need charms and wont spend on the lucky board a lot cause my magatamas are level 6 and some level 7...it would be nice if we get more adv threads and refines in events like this but it is what it is..
