Just 411 the MAC palettes fit other brands as well, so you can still use them instead of throwing them out if you use some others that fit. I have 3 or 4 different brands in mine & just have the palettes separated into types (matte neutrals, matte brights, lighter "shimmers" & deeper "shimmers.)

I need another 1.5" palette. I'm waiting for my last CC payment to clear so I can hit up CRC again lol.
