I just picked up some of the new microchangers they all have stress marks where the hand pegs into the arm.

 

That's been a problem with Kreons since the beginning of the line.

 

All of my preview wave Kreons were fine.

 

Its kinda hit or miss with them honestly. I have some that have the stress marks and some that dont. It just seems to be random IMO. Like the Vehicon kit, 2 of the Vehicons had them and 1 didnt?!?!

 

None of my first wave had them, until I put the hands in..

side note, where did the 2x4 pieces with Kre-O written on them, come from?

 

TRUE! IT IS a HIT OR MISS!

mine has the same with the first wave of kre-o and then the next wave which were the quest for energon and i got none that had stress marks!

 

All of the new micro changers come with that block now.

And it really is hit or miss with the stress marks. I've had some with it and others without but luckily none that have broken.

 

Yeah it's a common problem.

 

do they cause that much of an issue? If you don't move the hands much they look like they should be fine

 

Every single one of my Kreons have varying levels of the stress marks on their arms. I've moved all their hands, they don't break or seem to get worse so at this point I'm not too terribly worried about it. If they start to crack I'll stopp fiddling with the hands.

 

Haven't checked my other vehicons, but CJ and one vehicon have this issue.

I remember lego minifigs from back in the day had this issue to. Pop the hands in an out too much and you might end up with a nice crack right up to the elbow. Kreon wrists are thinner though so it's just the price to pay when trying to make something that small.

I wonder though would boiling the arms fix this?
