We are rather dubious, though, of the claims that these bottles give "more control" than a bag; it looks like you would trade in fine control for slightly easier use. What do you think?
From SLT: The kit includes two tall decorating bottles, three short decorating bottles, five steel decorating tips (round, ribbon, leaf, star and basketweave) and a frosting spatula. From looking at photos of the kit up-close, these tips appear to be standard tips that would also fit a normal coupler and decorating bag. This also means that you may be able to use other tips on these bottles as well.
