OwalaFreeSip C03766 Insulated Stainless Steel Water Bottle with Push Button and Built-in Straw, 710 ml, Very, Very Dark

Does the 40 oz fit in most car cup holders?

Do you have to flip the carry handle to press the button? I’m hoping to throw this in my kids backpacks but i don’t want things to hit the button?

Does the 24oz bottle fit in standard car cup holders? (I know the 32oz doesn’t.)

Replacement sealant for the sip n swig? The one we have gets all dirty even though I consistently wash them. Looking for replacement parts
