Women's Birkenstock size 38

Nearly brand new, these Birks were a gift to me from my sweet husband...they just are not the correct size for me. I've worn them a handful of times around our home in an attempt to convince myself I needed to let them go. Brand is BIRKENSTOCK Style is Mayari Size is 38 I do not have the original box, but I will absolutely ship in comparable packaging. I ship quick!
