Product Name: T-Juban (undershirt), Han-Juban (half undershirt), Juban, Japanese Clothing Accessories Brand: T-Juban Material: Main body - 100% cotton; Han-eri (collar) - 100% linen, with a Han-eri of Koshijichijimi Ro (a type of linen) Color: White Size: L, see image Purchased from: Tanaka Waso on Rakuten Description: Collar stiffeners can be inserted. The Han-eri cannot be replaced. I bought this thinking that a T-shirt type Juban that you just slip on would save time when dressing. It usually costs around 6,000 yen. The Han-eri material was specially ordered to be Koshijichijimi Ro. Koshijichijimi Ro Han-eri is a high-quality item and is very expensive to buy. People who use Koshijichijimi Ro Han-eri are likely to be serious kimono enthusiasts. I wanted to wear it myself, but the texture of the T-shirt-like fabric felt tight and hot, and it didn't work for me. Unfortunately. It's a waste to throw it away, so I hope someone else can wear it. Washed before listing. Using a hypoallergenic, additive-free liquid detergent (a high-quality detergent that can be used by babies, people with atopic dermatitis, and sensitive skin). No fluorescent detergent used. No strong artificial fragrance fabric softener used. Only the above additive-free detergent. The main body has yellowing. There is yellowing on the collar. ← I think the yellowing on the collar can be removed by washing with a stain remover. Worn twice. I don't know why the yellowing appeared even though I washed it immediately. I washed it again when listing it, but the yellowing did not come off. I think the yellowing on the collar can be removed by washing with a stain remover, etc. If you are concerned, please wash it before wearing. There is a feeling of wear on the armpit area. I don't know why it feels rubbed even though I only wore it twice. Please purchase with the understanding of this condition. New T-Juban is not cheap, so why not buy this one first and see if it suits you? If it does, then consider getting a new T-Juban. It would be a waste to buy a new one for around 6,000 yen and find that it doesn't suit you, like me.
