Proenza Schouler PS1 Bag

Gorgeous leather PS1 bag from Proenza Schouler. I believe it is size medium but I am not 100% sure. I am not the original owner so not sure when it was purchased. Since I’ve had it I’ve worn it maybe twice, but have stored it stuffed to keep its shape and recently washed and conditioned the bag. Has all original hardware. It has some wear from regular use, and slight discoloration on the top of the bag as pictured, but overall is in very good used condition. Please comment with any questions you may have!
