I would like to order 2 different types of Bento sets to be delivered together. How do I do so?

You have to fulfil the minimum pax required for each type of Bento when ordering more than 1 type. Do note that the maximum number of types of bento per order is 2.
For instance, the minimum number of sets required per order for our Inspire International and Inspire Signature is 15 sets. Hence you would need to order 15 sets of Inspire International and 15 sets of Inspire Signature (30 Bento sets in total). 
Some other examples include:
20 sets Impress International + 20 sets Impress Signature (40 sets in total)
25 x Amaze International + 25 x Amaze Signature (50 sets in total)
