This is a popular TENERITA Amunzen Back Gauze Pajama set. I received it as a gift and opened it, but I don't think I'll use it, so I'm selling it as is. It's a new, unused item with tags, but I took it out of the box and unfolded it. There are also many fold marks. The box also has some scratches, so please consider it as a bonus. Please refrain from purchasing if you are sensitive to these details. Also, since it will be shipped from Okinawa, an island, it may take some time to arrive, so please refrain from purchasing if you are in a hurry. The following is an excerpt from the website: This product is a unisex design. It's a double-woven pajama set with Amunzen (pebbled weave) on the outside and soft gauze on the inside. The breathable fabric with a "shibo" texture feels cool and refreshing, perfect for spring and summer wear. Amunzen Back Gauze is carefully bleached using the traditional "Wazarashi" method before the fabric is dyed. Compared to Western bleaching, this method takes time and effort to slowly process the fabric, without putting a strain on it, bringing out the natural fluffiness and gentle texture of the cotton. The material also becomes softer with each wash. The simple stand-collar shirt is an oversized design that can be worn by anyone. Paired with the shorts that flare out slightly towards the hem, you can enjoy a comfortable time even in the hot season.
