Recommended for those who want a slight indentation on the shoulders, but find the front being too long to be a hindrance (*^ω^*) This is the Special Type ②, Normal Type. The outer fabric is 10oz denim in purple. It's a denim with a good thickness yet soft feel. It doesn't have the rough, stiff texture often found in cheaper denim. The inside is USA cotton. The flap length is 31cm. It comes with 3 buttons! Fully lined and reversible.
