I'm wondering when the delivery is expected to arrive.

I’m planning to order samples through the Naru Box now, and I was wondering approximately how long the delivery usually takes. I’m currently in the U.S., so if I place the order from the U.S., could you let me know roughly how long the shipping would take? I have some other plans coming up and would like to receive the samples as soon as possible. If it usually takes around a month, I may plan my order around my schedule and place it on a different date. So if you could let me know the estimated delivery time, I’d really appreciate it! Thank you in advance!
