Let's go through the Adeptus Astartes Inceptors magnetization upgrades.
First you'll want to replace the worst flight stands Games-Workshop has ever made with our custom posable magnetic flight stand kit. The base kit is a medium small posable with a custom bit that is just for the Inceptor.
For those of you looking to use a magnetic case, you'll want Large Thick Flush-Fit Basing Magnets.
If you want bases that have magnet holes embedded in them grab the 40mm bases here.
