I recently got this hot water bottle and it is easily the best purchase I’ve made all year. It’s a classic rubber design that allows the heat to transfer from the water to its exterior and it comes with a cable-knit style cover that makes it look like it’s wearing a sweater. The rubber is not very pleasant to hold, especially when it’s hot. The cover fixes that, while also being very aesthetically pleasing in a Wes Anderson sort of way.  The effect is that when I’m sitting in my dorm, I have, in effect, a portable coziness machine. Between its heat and the softness of the sweater, my hot water bottle is making my winter a lot more pleasant.
