30MF Customize Structure 2

I mainly got the set for the "bear trap" which is essentially a mechanical mimic that you can fit inside of a 30MF treasure chest (though the fit is a little loose).

The rocks are nicely sculpted, even if the seam lines are a little awkward. They also don't match the rock from the 'Customized Structure 1' kit.
There are 3mm hard points on the pillar, so you can put something like the torch from the Quest set on it, and the tip of the middle rock comes off so you can sit on it, or attach something to the hidden 3mm hard point.

There are 3 critters in this box:
Bear trap mimic - As noted you can put it in a treasure chest, it has two eyes that turn separately and two coils that come off
Sonic Bat - Largely static, but the wings turn and the ball joints are small enough that you can put the wings into 3mm hard points, such as on a helmet for extra style - Has a 3mm peg on the back to slot into the pillar so it looks like it's airborne
Tentacle Crawler - 3 piece monster with its eye, stalk and tentacle legs - you can attach it onto other things, but it tends to tip over

All in all it's a decent kit, since you can use the items for diorama pieces and the critters as background props, rather than main monsters that the characters fight against.
