Frequently Asked Questions

Can I use these coaster blanks with HTV or laser engraving?

Yes. The bamboo surface accepts sublimation, HTV (heat transfer vinyl), and laser engraving. For sublimation, use the settings above. For HTV, follow your vinyl manufacturer’s temperature and time guidelines.

Is the bottle opener removable?

No. The stainless steel opener is permanently recessed into the back of the coaster. This keeps it secure through hundreds of uses without loosening.

Do the coasters come individually packaged?

Coasters ship in bulk packs of 24, 36, or 60. They are stacked with protective layers between pieces to prevent surface scratches during transit.

What is the best size for sublimation?

The round 3.03in (7.7cm) is our best seller — it provides enough print area for logos and short text while remaining compact enough for standard mug presses and heat presses.

Are these food-safe?

The bamboo surface is natural and food-safe. However, we recommend sublimating only the coaster surface (not the side that contacts beverages directly) and avoiding sublimation on surfaces that will touch drinks.
