When I first unboxed these mini katanas, I was genuinely impressed by their metal construction. They have a satisfying weight to them and the detailing is spot-on for anime fans. I immediately recognized them from Demon Slayer - such a cool little collectible!

However, the sheath issue is real. Like other reviewers mentioned, mine wouldn't stay put at all. I tried the paper trick (crumpling tiny bits inside the sheath) which helped somewhat, but it's still not perfect. It's frustrating because the keychain part is attached to the sheath rather than the sword itself.

I ended up using mine as a bag charm instead of a keychain - they're surprisingly large for that purpose! The metal blade does have slightly sharp edges (nothing dangerous, but noticeable), so be careful when handling. My nephew keeps trying to duel with his friends using these - they make perfect pretend weapons for play fights.

For display purposes, these look amazing alongside my other anime merch. I've got mine standing upright on my gaming desk and they catch the light beautifully. Just don't expect them to function perfectly as actual keychains unless you're willing to do some DIY fixes.
