NOT A TEACHER
This non-teacher respectfully offers these ideas:
(a) She sent a chocolate box to each of her friends. (That is, a box made of chocolate. What a delicious gift!)
(b) I would avoid this phrase.
(c) The teacher is very popular because every Friday he brings a big box of
chocolates to class as a reward for the students' hard work that week.
(d) I would avoid this phrase.
(e) He has just returned from Cuba with a box of Havana cigars.
I would have assumed a box made out of chocolates.
A cookie jar = a decorative container for cookies
A candy dish = a dish you keep candies on
A chocolate box = a box made from chocolate. I've never heard of a box just for keeping chocolates in it. I wish I did. And I wish some magic elf kept it full all the time.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
