SUIT SELECT Men's Dress Shirts - Summer Short-Sleeved Dress Shirts Product Number: EXBL20-01_T Color: White Size: M39 Purchased: 7/20 New, Unused Purchased for: 5,390 yen Receipt Number: 901261937439998671447 You can search the SUIT SELECT official website using the product number: EXBL20-01_T, and the product will be displayed. -------------------------- My family bought this for me last week, but due to a physical condition, I can only wear 100% cotton, so I am selling it. I didn't realize it was a 4S and removed the tag with the product number and threw it away, but it is new. I plan to ship via Nekopos (domestic delivery service). Due to the size, I will remove the collar stays before shipping. Short-sleeved shirts are only available in S/M/L sizes, without detailed size variations, so many people buy the size they usually wear for long-sleeved dress shirts. It is cheaper than buying it in the store, so I hope you will consider it.
