a cart is a cart??

A 901 cart, is a 901 cart correct?? There is no difference when ordering blank carts so least expensive is the way to go, right??

blanks have no liquid inside other then that there the same.

The only difference is between whistle tips and round tips. Even then, the only difference is the shape of the tip. The actual liquid reservoir is the same.

Some 901 carts are shaped like "[]" inside.
Others are shaped like "D"

(unless they've quit selling one of them)

It just depends on what you like. I like the "D" shaped ones. I can't get my straw and filling both in the "[]" shaped ones. They're smaller diameter.

Yeah refilling carts is the best way!
