The unique combination of the grounds is the "stone pavement joint" in the photo on the left.
Even if there is a gap in this part, it may cause water to leak.
We developed a unique technology of "pressure combination" to combine this part. Machine pressure is applied evenly to the wooden material of the set.
For this reason, the combination is achieved with absolutely no gap as shown in the left picture. There is almost no risk of leakage compared to other products.
Break the mirror and toast it with baru sake. If you have a leakage at these times, you will ruin your guests outfit. There are many others that are made by other companies.
But you dont have to worry about our pressure-matched barrels.
