This is MAC's only train case. It has three tiers (four including the bottom). The "trays" are very sturdy (so your makeup doesn't crash down). Although I have a "makeup table", I use train cases to store my eyeshadows, blushes, palettes, etc. This also has a lock!!! Overall, a very good train case (unlike Sephora's which I feel are poorly made and fall apart easily). The only complaint I have is that it's really heavy (hence it is sturdy). Also, others have complained that it tips over easily. A solution to that problem is to put the heavier items on the bottem (top shelf lightest, bottem self heaviest). I've had mine for about 6 years and it's still like new. A great investment!
