The best tool box foam inserts depend on your drawer or case dimensions, desired padding thickness, and whether you prefer to cut custom outlines or pluck pre-scored sections. The ONREVA 22-by-18-inch sheets suit larger storage areas, while its 16-by-12-inch sheets fit smaller projects. For tool-free customization, the pre-scored grid foam is the clearest choice. The products below compare sheet size, thickness, material, and customization method.

ONREVA 16 x 12-Inch Foam, Four-Pack
This ONREVA set includes four 16-by-12-by-1-inch high-density polyethylene foam sheets in black with red. The sheets are designed for custom tool outlines: mark the shape, then cut it with a blade or hot knife. Individual recesses can give tools designated storage spots and help keep them from colliding during storage or transit.
Best for: people organizing a compact drawer, case, or tool area who want to plan their own layout. It was selected as a practical small-format option with four sheets for multiple inserts or attempts. Limitation: customization requires cutting, so it is less convenient than foam with pre-scored sections if you want a no-tool setup.
ONREVA 22 x 18-Inch Foam, Four-Pack
These four sheets measure 22 by 18 by 1 inch and use high-density polyethylene foam. The larger footprint provides more area per sheet than the 16-by-12-inch options, which can help when laying out a collection of tools or covering a wider drawer. The material can be cut to create fitted spaces for individual tools.
Best for: buyers with a larger case or drawer who want to make custom tool shadows without joining smaller sheets. It was selected for its larger listed dimensions and four-sheet package. Limitation: its one-inch thickness may not suit every tool or storage depth; measure the available space and the items before cutting.
Pre-Scored Grid Foam, Mixed Thicknesses
This four-piece set includes 16-by-12-inch sheets: two are one inch thick and two are 1.5 inches thick. Its 0.6-by-0.6-inch pre-scored grid is designed for hand removal of foam blocks, so users can form compartments without cutting tools. The listing describes high-density polyurethane foam intended to cushion items and absorb impact and vibration.
Best for: buyers who value quick layout changes or want different listed thicknesses in one package. It was selected for its pluckable grid and mixed-thickness assortment. Limitation: the grid fixes the layout to its pre-scored spacing, so it may not produce the same precise outline as careful blade-cut foam.
ONREVA 16 x 12-Inch, 1.5-Inch Foam
This ONREVA four-pack provides 16-by-12-inch sheets that are 1.5 inches thick. The high-density polyethylene foam can be customized by outlining tools and cutting the desired recesses. The added thickness compared with the one-inch ONREVA sheets gives buyers another depth option when planning an insert.
Best for: people who need a thicker sheet for a custom-cut tool layout. It was selected to offer a direct thickness comparison within the same ONREVA product style. Limitation: thicker foam takes up more vertical space, so check the drawer or case depth before choosing it.
ONREVA 16 x 12-Inch Foam, Alternate Listing
This listing describes four 16-by-12-by-1-inch high-density polyethylene sheets, matching the dimensions and customization features of the other one-inch ONREVA option. The foam can be cut to create tool-specific recesses and designated spots intended to help keep tools organized and separated.
Best for: buyers comparing the available listings for the same general sheet format or planning a compact custom insert. It was included as another listed option with the same stated size and pack count. Limitation: the provided specifications do not identify a functional difference from the other 16-by-12-by-1-inch ONREVA listing, so compare the listing details before selecting.
Buying Guide: How to Choose Tool Box Foam Inserts
What sheet size fits your drawer or case?
Measure the inside length and width of the storage area before selecting foam. The listed ONREVA sheets come in 16-by-12-inch and 22-by-18-inch formats. A larger sheet can cover more area, while smaller sheets may be easier to plan around a compact case. Check the product dimensions against the usable interior space, not just the outside dimensions of the toolbox.
How thick should the foam be?
Compare the sheet thickness with both the available vertical clearance and the tools’ height. The listings include one-inch sheets and 1.5-inch sheets. Thicker foam may allow deeper custom recesses, but it also uses more drawer or case height. Avoid assuming that one thickness fits every toolbox; measure the storage space and consider how much material you plan to remove.
Should you cut outlines or pluck a grid?
Choose cut-to-shape foam if you want to trace each tool and create a more tailored arrangement. The ONREVA options are described as cuttable with a blade or hot knife. Choose the pre-scored grid if hand-removable sections and tool-free customization matter more. Its fixed 0.6-inch grid is convenient, but the resulting compartments follow that spacing.
Which foam material and package details matter?
Check the listed material and number of sheets. The ONREVA sheets are described as high-density polyethylene; the pre-scored set is described as high-density polyurethane. The pre-scored package includes two thicknesses, while the ONREVA options are supplied in four-sheet packs of one specified size and thickness. Compare these details with your project before buying.
Frequently Asked Questions
Can tool box foam inserts be customized?
Yes. The listed ONREVA foam can be outlined and cut to create tool-specific spaces. The grid option can be customized by removing pre-scored foam blocks by hand.
Which option does not require a cutting tool?
The black and gray pre-scored grid foam is described as customizable by hand. The ONREVA sheets are described as requiring a blade or hot knife for cutting.
Are one-inch and 1.5-inch sheets interchangeable?
They have different thicknesses, so they are not interchangeable for every storage setup. Measure case depth and tool height before choosing.
How do I choose between the two ONREVA sheet sizes?
Choose 16-by-12-inch sheets for a smaller layout and 22-by-18-inch sheets when the storage area needs a larger sheet. Confirm the interior measurements first.
Does the pre-scored foam make exact tool outlines?
It allows compartments to be formed by removing grid blocks. Its 0.6-inch spacing may not match the precision of a carefully cut outline for every tool.
