This guide to storing your Lego collection does not recommend these storage bricks:
Unfortunately, it is a deeply flawed product — small LEGO parts get stuck in the grooves (such as 1×1, Minifigure accessories, and Cheese Slopes).
Beyond this critical issue: they are really expensive, have square corners on this inside (making it harder to get small parts out of the box), the bright colors exactly match official LEGO colors (making it harder to find parts in that color), are not wide enough to spread parts around to find what you are looking for, and while the lids are hard to remove they don’t latch closed for travel.
