I can't vouch for those sellers, but before seeing those I paid more to someone else, $30 with $12 shipping Argh!. However, I'm very happy with what I got and they sent it quick, brand new sealed.
There's 12 full color boxes inside and in each one is a single figure or a double figure combo doing a move.
The random figures I ended up with were two of each. Counting combos as 2 I got 16 figures (all 8 different) from the 12 boxes. Got a flesh of each except a full color painted Kinnikuman Great (it's nice to have one that looks more noticeably different from Suguru Kinnikuman). And then either a red or blue of each. Maybe this reveals some of sort of pattern you're likely to have as the ordering inside the box as I opened them was very uniform: The two of each in the different colors being in side by side boxes with singles in the front and combos in the back. The two that it's possible to get colored figures of were the front two rows.
These seem very premium quality and material seems closer to M.U.S.C.L.E. but still a bit softer and more flexible than it.
A bulky Brocken Jr (no armbands to worry about if you're looking to avoid those) doing Red Rain of Pain to the most beastly version of Mr. Khamen I've seen.
Certainly the most beastly version of Mammothman, though I can't decide which version of him I like best.
Robin Mask simply shirtless with helmet doing tower bridge to Kinnikuman are good quality but not so much detail to write home about.
A great Kinnikuman Soldier though I still like the M.U.S.C.L.E. (A) version a little more - possible to get full color version.
Prism-man - bulkier than original, actually my least favorite of these characters. I just don't find him as interesting regardless of the quality.
A straight forward but good Kinnikuman Great version I was fortunate to get full color.
I think the Mammothman and Mr. Khamen in this set are its best figures after the possible full color two.
Some heads are proportioned larger than the original Kinnikuman/MUSCLE and others are closer to regular size.
The volumes actually called premium look to be a yet another step above this though I haven't seen them other than pictures. I think people should be pleased with this box of figures especially if you get it around $30 with free shipping.
