This product came to me first as a small free sample suitable for one shower.I was impressed and wound up ordering the 250 ml bottle from Amazon.It is pricey,but if used sparingly(it seems to be very concentrated) should last for some time. I would give it a five star rating ,except for the bottle that is comes in. Not transparent so have no idea how much is left in it, but more irritating is that the bottle is square and very firm.So squeezing the soap out of the bottle becomes somewhat of a strength contest. Manufacturer should give up style for practicality in this case.
Update Jan.2013 ,here s a solution to the several comments about the square bottle the product is packaged in,my review included. Buy a bottle of Men-U Leave in Conditioner from Amazon,http://www.amazon.com/Men-u-Smooth-Leave-in-Conditioner-2-5oz/dp/B002UDZSDY/ref=sr_1_5?s=hpc&ie=UTF8&qid=1359315546&sr=1-5&keywords=men-u . use it and when the container is empty put the Kyoku in the Men-U container .With a permanent black marker mark the Men-u bottle "BW" andd you are good to go. The Men-u container also is square (2.5 oz) but it has a pump and can be carried onto an airplane in your carry-on. The pump works just fine delivering the Kyoku. And a bonus is that the Men-u you purchased is a great product too.
Update June.2013 Recently decided to try this product one more time ,in spite of the user unfriendly container.Ordered Kyoku - Fire this time. The best way I can describe the scent is while bathing it is a scent comparable to a very strong sandalwood aftershave lotion. Sudzing for bathing is poor. And of course the container is problematic at best.(See above for a remedy)As another Review points out ,correctly, the scent diminishes and disappears within minutes of leaving the shower.Not a bad thing given the onerous scent to begin with. I wound up throwing the essentially full container out and returned to what has always been a far better product in terms of scent,container,sudzing and cleansing , Men-U Ultra Concentrate shower gel, $12.99 for 3.3 oz. ,found here at Amazon. I would now rate Kyoku one or two stars at best. Too expensive for a product that is mediocre and not user friendly.
