Wholly Molly! These things are big. I got a hold of these things thinking they were DVDs, as the promo shots of them had a case that looked like a DVD slipcase cover. At no point was there a size reference though. They arrived in a big box and BOOM - huge VHS packs. Each one contains 2 VHS tapes, with 2 eps each. Officially licensed items in Korea. For reference, that is Masterpiece Grimlock holding those things up. I don't even own a VHS player anymore, but they do make some great display pieces.
Previously, we had this cover art listed on the site as a DVD. After some further research, it looks like that was false, and they were only released on VHS. If you know different, feel free to correct us!
There are 3 pics at the end, they are from Korean search results that I came across a while ago. Not sure if they are bootleg, or perhaps they were rental store versions.
