These are the pens I'm using to keep track of my schoolwork while we're social distancing. I've had them for a couple years, and they've always served me well whether I was taking notes or just writing. I used lined paper to complete the whole "school" vibe. There's no real reason for the colors other than the association with my classes. They are inherently colorful, however, which makes for a good subject.
My mom got these little guys for me for Christmas. We have a liking towards the seasonal birds that Target sells, so she got me mini ones! I have a few full-sized, and I actually got her one for Christmas, too. It was pretty funny that we essentially got each other the same thing. I've kept them around my room ever since--even though it's only been a couple months.
