Sublimation Coasters MDF Cork Back 72 PCS - Bulk Square Blanks

Our review of these sublimation coaster blanks finds them best suited to hobby crafters, event planners, and small makers who need a large, consistent batch of printable coasters. The single biggest reason to buy is quantity paired with functional build quality: 72 square MDF coasters with cork backs provide enough blanks for parties, seasonal gifts, or a succession of experiments without running short. The set is practical for anyone doing heat transfer decoration and offers a consistent substrate that produces clear, vivid patterns when used with proper sublimation paper and heat settings.

Key Features

• Bulk quantity: Seventy-two coasters in one pack means you can produce many gifts or sell finished items without repeated restocking trips.
• Standard size: Each coaster measures about 3.93 in x 3.93 in x 0.16 in, a common square size that fits most cups, mugs, and glassware.
• Sturdy construction: Made from MDF with a cork backing, the blanks resist deformation and provide non-slip stability on tables and countertops.
• Heat transfer ready: A coated surface accepts heat transfer sublimation for clear, vivid images when pressed at recommended temperatures and times.
• Water resistance and insulation: The materials offer waterproofing and good thermal insulation to protect surfaces from hot drinkware.

Who It's For

This pack is ideal for craft entrepreneurs, wedding and party planners, teachers running group projects, and families preparing seasonal or holiday gifts; the large 72-piece count removes the need for frequent reorders. It also suits crafters who prioritize uniform size and material when testing designs and color transfers.

Those who should look elsewhere include single users who only need a handful of coasters or people who prefer ceramic or stone coasters for a different aesthetic or heavier weight; this product is a lightweight MDF option built for customization rather than heavy, decorative permanence.
