TWSBI ECO Fountain Pen ~ Cerulean BlueTWSBI fountain pens are beloved for their clear barrels (sometimes called demonstrators) that allow users to see the ink inside. The pen has an interior ink filling piston system that holds much more ink than a typical fountain pen cartridge. It also allows you to fill your pen up with ink without the use of a converter. Just unscrew the cap at the end of the pen, dip the pen into ink, fill, and screw the cap back on. The TWSBI ECO (for "Economical")

I often have trouble with sports bra bands feeling too constricting (for size 34C), but this one was comfortable enough to wear right away and I can tell it will get comfier as I wear it. I am 5’7, 130 lbs and bought a medium. The color is vibrant and the material feels high quality. Straps are not adjustable but that hasn’t been a problem up to this point.

Good price, does the job

Size: Large, Color: Emerald Green, Size: Large, Color: Emerald Green

I love the way this fits. I’m probably a C cup on a good day and just under 200 lbs. I wear this for my workouts (elliptical and weight lifting). It stays in place, has kept up in my chaos washing, and is super cute.

Cute but not very supportive

Size: Large, Color: Navy

This bra is cute but it’s not very supportive. I’m a 34DD and it gaps on the sides and the straps are too long even though I have a long torso. I’m not even sure that I’ll wear it low impact activities, probably just day to day wear.
