if you're just looking for a mesh grip you can get this one http://www.mybadmintonstore.com/shop/product_info.php?cPath=25_29_51&products_id=825 and that store has free shipping worldwide. i'm also looking for a place where you can buy the ac105ex grip but i don't know of places online to get it
Many thanks Jmore! Out of curiosity, what is the difference between the grip in your link and AC105EX?
the grip in the link has "Twin Rib Backing" which is like two raised strips so you have better grip. you can kind of see it on the packaging of the grips. the AC105EX is just a flat grip without the ribs. also the grip in the link only has one grip in a pack whereas the AC105EX grips come in a pack of three.
