Colorful PoPoTumbler Handle for 20 oz Yeti Rambler Cooler Cup, Rtic Mug, Sic, Ozark Trail Grip and more (20 Oz, Black)

I want 2 different colors but checkout won't let me

Will this fit the Boelter 20 oz coffee travel mug?

What is the radius of this lid?

Will this handle fit an indent on the cup? I think this cup might be called a Rambler style...same as in this picture above.
