Found these products on Yonex JP web site and some other chinese forum

Yonex BAG751W

Unfortunately you might not be able to find these in SEA countries.

I think there should be some shops import them from Japan. Especially shops at HK and SG, just wish that some Yonex fans can provide some info. :)

I know that shops in HK does not stock these items. Even shops like Victoria and Windsor Racket Shop in Tokyo don't stock them. If you really want it, you'll probably have to get it here... http://shuttle-house.com/page_top_ENGLISH/MAIL_ORDER/Meker_Catalog/07_YONEX/MIDDLE/P079.html

Hi Ar Dan-

Thx for the information.
Is shuttle-house.com a Japan web site?

I have not come across any of these in Singapore or Hong Kong.

And yes, shuttle-house.com is a Japan-based web site.

YOu can ask Matt. I think he ordered from them before several times.
