Buying tips
- Closed-cell polyethylene foam resists moisture better than open-cell polyurethane, which matters most if the case will see humidity or occasional rain.
- Pluck foam is faster and cheaper to customize by hand; laser-cut custom foam gives a tighter, more precise fit but costs more and takes longer to arrive.
- Leave a little extra clearance in the cutout rather than a bone-tight fit — foam compresses slightly over time and a too-tight pocket can make removing the item harder.
- If replacing foam in an existing case, measure the interior cavity (not the outer case dimensions) before ordering a pre-cut insert.
