This one has been driving me nuts for at least 2 years. Core magazines
publishes a lifestyle magazine called "Burst". I saw a couple of
issues a few years back, but its just not available in the US, and
they won't ship it from Japan. The large Japanese booksellers, such as
Kinokuniya, won't order it, I think because the publisher, Core
magazine publishes a lot of soft and not so soft core picture and
anime magazines. Kinokuniya can't or won't order it for me and I've
been to 3 different outlets in So Cal and Portland. Burst is not a
porno magazine. There are three or four different magazine published
under the Burst banner. Burst, Burst High, Burst Tattoo and some
special Body Mod books. Once in a blue moon you'll find a copy of
Burst Tattoo on E-bay and there are a few places where you can get the
Body Mod Books, but the one I'm interested is Burst. I will purchase
as many back issues as i can get hold of, new or used. In addition to
the question price I will gladly pay a finders fee for someone who can
facilitate this. The magazines are expensive between 9.00 and 18.00+
dollars, depending on the issue

I've also tried online Japanese used booksellers, but since I can't
read or write Japanese I'm not having much luck
