Bearbrick blind boxes are among the most fun to collect. There are so many designs in each series and then on top of that, there are variants and “secret” figures, some of which can be extremely rare (and therefore exciting) to get. They are only sold in Japan and no resellers based in the USA can stock them at wholesale which drives prices up. Yet, some available at BlindBoxes.com are available for as little as $7.49. Most are under $10, with the exception being those that are very old and long out of print.
Some open items still remain, though BlindBoxes.com does not plan to open more, so get them while you can!
