Blue Contigo mug with octopus sticker

I lost my blue Contigo travel mug yesterday around 4:15pm near the Covered Market on Cornmarket Street in Oxford. It's a 16-ounce stainless steel mug with a matte blue finish, a black lid, and a red button you press to open. On the bottom there's a small white octopus sticker I stuck there myself, plus a faint coffee ring stain around the rim from daily use. It’s a little scuffed from being banged around in my bag, but it still keeps heat surprisingly well. This mug is sentimental because it was a gift from my aunt overseas, and I really need it back. If you’ve seen it, please message me—I’ll swing by the Market or the university library to pick it up.
