Cup Holders Black Plastic Boat Rv Car Truck Inserts

It works but too shallow.

work great

they are 2.7 inches at the mouth opening. It'll work for a soda can, but is close, but not right for a Starbucks large coffee cup. I think I need to find something with a 3inch opening.

Fit exatly what I needed. Was missing one for a long time. Now I have both in my RV. Couldn't find this one size anywhere at brick and Mortar store. Thanks
