Vincent, just keep doing whatever you are doing my friend, it's obviously working! Large gator gars would be a perfect fit for large portions of food, such as these.
My acquaintance is a regional rep for Hikari here in CA and after seeing him at multiple trade shows over the years I would be incredibly surprised if these weren't legit. The guys car is loaded with Hikari food bags and samples.I've searched the Hikari site and around the internet and can't find any whisper about these large wafers. This guy wasn't showing you something home made, was he?
