Lay them flat!!! They’re going to sweat but they’ll be fine if they are flat. Indoor in the coolest place possible if it gets hot where you are.

I’ve had these Alex drawers for years so I repurposed and use it for my wax storage! I can fit 7 across, 3 deep, stacked 2 high (42 per drawer). They lay flat and it’s easy to see the second layer. You could fit more going the opposite direction in the back, but it’s hard to see those because the drawers don’t pull out ALL the way. The bottom three drawers are deeper so you can fit 3 high. I only do that for my backstock drawer (bottom drawer). The top 4 are all wax by scent families and the 5th is pods and a couple bricks. I also have several bars in the garage although that’s prob not the best place for them!
