Hirota Belt B-401 Special Blue Satin Shushi
I bought both the red and blue versions, and they are quite simply the best quality belts I have ever owned. The personalised embroidery is excellent and I particularly like the electric blue colour.
They took a week of constant tying and untying to wear them in and be careful to buy 10cm longer than normal as the knot is slightly larger, but these are small prices to pay for such a quality product.
Thank you Hamid!!!
