Choosing rotary cutting tools & mats is really a choice between a work surface and a cutting consumable. If your quilting table needs protection, alignment, and angle guides, the self-healing mat is the relevant direction. If your existing setup needs replacement blades for an OLFA 45mm rotary cutter, the blade pack addresses a different bottleneck. The practical answer is to match the purchase to whether your next cut needs a surface or an edge.
Quick verdict
Choose the Self-Healing Cutting Mat 18 x 12-inch 5-Layer Double-Sided Rotary Mat when you need a marked, non-slip workspace for quilting and fabric cutting. Its grids and angle markings support accurate layout, while the double-sided design gives the mat two usable surfaces. At $15.05, it is also $34.90 below the blade pack.
Choose the Pack of 4 OLFA 45mm Rotary Cutter Blades 40 Pack when you already use an OLFA 45mm rotary cutter and need a larger blade supply. Its stated six-layer cutting capacity and storage/disposal case make it a focused blade purchase, but its condition is listed as Used.

Where each product wins
The self-healing mat wins for workspace setup
This is the clearer fit when the table is the problem. The non-slip surface, printed grid, and angle markings are directly relevant to rotary cutting tools for quilting, while the description also positions it for sewing, fabric, vinyl, leather, and other craft work. Its five-layer, double-sided construction and toughened inner core are aimed at protecting the tabletop and extending blade life. The 18 x 12-inch A3 format is described as fitting most desks and workstations, making the use case easy to understand: a marked cutting surface for a compact sewing or craft area.
The OLFA blades win for a blade-replacement need
The blade pack makes more sense when you already have the compatible cutter and want replacement edges rather than another surface. The description specifically says the 45mm blades fit any OLFA 45mm rotary cutter and includes a plastic storage/blade-disposal case. That makes it a more targeted choice for maintaining an OLFA-based cutting setup. It does not solve a need for table protection, grid markings, or angle guides, so it should not replace a mat in a new quilting workspace.
Product notes
Self-Healing Double-Sided Rotary Mat
The Self-Healing Cutting Mat is the practical pick when your quilting setup needs a protected surface with built-in guidance. Its 18 x 12-inch A3 format is described as fitting most desks and workstations, and the non-slip surface is paired with printed grids and angle markings for fabric and craft cuts. The green-and-black, double-sided PVC construction is described as a five-layer design with a toughened inner core, and the mat is intended for sewing, quilting, leather, vinyl, model building, art, clay, and scrapbooking. At USD 15.05, it sits $34.90 below the blade pack. The limitation is its defined 18 x 12-inch footprint: larger pieces may require repositioning, and the included component is the mat itself rather than a blade replacement.
OLFA 45mm Rotary Cutter Blades, 40 Pack
The OLFA 45mm blade pack targets a shopper whose rotary cutter is already an OLFA 45mm model. The description identifies tungsten tool steel, says the blades can cut through six layers at once, and includes a plastic case for blade storage and disposal. Its 40-pack format gives this purchase a replenishment role rather than a workspace role, while the Japan origin and silver color are part of the product description. At USD 49.95, it is the more expensive side of this comparison. The important limitation is the condition marked Used, which may not suit shoppers specifically seeking new cutting supplies. It also does not provide a self-healing mat, grid, or cutting surface.
Final choice by use case
- For a new or incomplete quilting workspace: choose the Self-Healing Double-Sided Rotary Mat for its non-slip surface, grid, and angle markings.
- For an OLFA 45mm rotary cutter that needs replacement blades: choose the OLFA 45mm Rotary Cutter Blades for their stated fit and blade-focused format.
- For the lower-priced purchase: the mat is the straightforward choice at USD 15.05.
- For a shopper weighing condition carefully: the blade pack is marked Used, while the mat is marked New.
These products solve separate parts of fabric cutting. Pick the mat when accuracy starts with the table; pick the OLFA pack when the table is ready and the cutter needs replacement blades.
