Gap Short-sleeved Knit 100% Italian Merino Wool A smooth knit. It is not itchy. There are buttons on the side. It has been worn a few times, so I believe the condition is good. It is thin, but because it is 100% wool, it is warm. Although it is 100% wool, it can be washed at home. The colors in photos 4, 6, 7, and 9 are closest to the actual item. Length: 53 cm Width: 37 cm Sleeve length: 30.5 cm Measurements are taken by an amateur. Please understand that there may be some errors due to the nature of knitwear. Merino wool is high-quality wool obtained from Merino sheep, mainly raised in Australia and New Zealand. Its fibers are much finer and whiter than regular wool, characterized by a smooth texture that is less likely to be itchy. It excels in heat retention, moisture absorption and quick drying, and natural antibacterial and deodorizing effects, making it a high-performance natural material suitable for all seasons, keeping you warm in winter and cool in summer.
