This is a Patagonia cotton plain T-shirt. The model number is 52010 PUM. It is an authentic item purchased at the Futako-Tamagawa Patagonia store for 8250 yen. The size is S, but it runs large. I've worn it about 10 times and washed it again for this listing. The actual color is a light beige, or a light cream color. The size is approximate, measured by hand: length 67cm, width 47cm, shoulder width 45cm. There may be some error, so please check the same product online for details. I am selling many used items as I declutter. Used items have a certain degree of wear and tear. Please consider purchasing only if you understand that these are used items and you are satisfied with the price and condition. Shipping will be via Yu-Packet Post, folded small for postal delivery. I will be listing many more items in the future, so please contact me separately for combined purchases. I cannot answer questions during the day, so I will respond in the evening of the day you comment, or the next day.
