It's DVD only (seasons 6 — 10 are the only seasons available on Blu - ray) and the two
digibook cases feature stiff paperboard sleeves rather than trays (which means fingerprints on the disc and a fears of scuffing when removing and returning them to the case), but it's a solid, substantial set.
Smallville: The Complete Series (Warner) is one of the most impressive TV box sets of the year, a collection of all 218 episodes and supplements, plus exclusive bonus supplements, on 62 discs in a box set of hefty
digibook cases.
