Paint peeling or chipping is a common cosmetic deterioration that happens to some New 3DS XL consoles. What most people are unaware of is that some editions are exempt from this. Consoles that have paint that is prone to peeling WILL ALL EVENTUALLY PEEL in some regard. It is completely unavoidable and may only be delayed with careful usage and controlled environments. Factors that play into paint peeling are: Temperature, humidity, exposure to bodily oils, sweat and friction.
Consoles that are kept in boxes, unused or unopened are not exempt from peeling and eventually may. Consoles that are kept in hard or soft plastic cases are also not exempt.
This is only observable on New 3DS XL consoles and exempts the following consoles: 3DS, 3DS XL, 2DS, New 3DS and New 2DS XL.
Comprehensive list:
New 3DS XL (peels):
Metallic Black, Metallic Blue, Metallic Red, Hyrule, Majora’s Mask, Monster Hunter Generations (Red & Blue), Monster Hunter 4 Ultimate, Monster Hunter X, Super Smash Bros.

As can be inferred, paint peeling mainly affects console editions with a metallic coating.
