While I was in Hawaii, I picked up two shopping bags, as omiyage for myself.
The first one was from Foodland, only US$1.99+tax (as long as you have their Maikai card otherwise it is a little higher), and it was so cute...Spam Musubi.
I actually heard about it from Pomai's post. His post also shows more photos of the bag.
This bag holds quite a bit.
The second bag was from Whole Foods, only US$.99+tax and it is HUGE.
While at WF, I also spotted Japanese tourists picking up the smaller bags, probably for omiyage (souvenirs) too.
Only thing about these two bags is that with this humid and hot weather, it sticks to me as I walk to and from the grocery store, so I'm going to use them this winter.
