Thanks for the reply! Logic dictates that yeah, they'd be too small to affect anything, but agh paranoid, heh.
The largest ones I've used so far are only about 5mm diameter x 2mm height, most of them are either 2mm or 3mm diameter. Got one pair holding each sponson in my land raider in, four pairs in my defiler, and a number of smaller ones in my terminator sorcerer.
Also trying to figure if they'd be okay for me to actually take as carry-on luggage, or if I'd have to put it in with the check-in luggage. Which I don't want to do 'cause augh, don't want to let my models out of my sight. D:
The magnets I used are from the ModiFX magnet starter pack
