50 PCS Sublimation Blank Cup Coasters Bulk, 4x4 Inch Round Blank Cup Mat Rubber for Sublimation Transfer Heat Press Printing DIY Crafts

Such a great deal and they sublimate gorgeously! The thickness is perfect and the size was exactly 4". I sublimated at 385° for 55 seconds and they came out amazing! Will be buying again.

These sublimated color beautifully!! Made these for a local bar and they loved them!! The size and durability are perfect for daily use! And for the price and quantity, I couldn’t be happier! Definitely will be ordering again!

These coasters sublimate very well. My colors came out bright and there was no problem with them during the heat press time. Do not press too long or the neoprene will start to show through! Good value.

I've ordered multiple bulk coaster sets from Amazon & this is the best quality I've had. These are significantly thicker than others and firm. Great quality.

Will purchase more of this item

I ordered these to sublimate for a local non-profit. They take any design and color perfectly. I found it best to make the design about an 1/8" larger than the coaster so there are no white edges. It has worked without issue. I only had 1 bad press out of all of the coaster and it was my fault. I will buy again if a business or charity needs foam coasters.

These have become my favorite thing to sublimate. They are really well made. I’ve had no issues and have done several hundred now. Will definitely buy more.

These coasters sublimated beautifully! I made several sets for Christmas gifts and put holiday drink recipes on them. The images were all super vibrant and great quality. I’ve purchased them multiple times!

great price good quality

Cumple lo que dicen y son de gran calidad

These are quite a bit thicker than other brands. Great vale for the price.

Sublimates well no issues. Did not find any defective ones to date.

These were easy to sublimated on and ink took well to them. I'd definitely buy again. I only wished that they would have shipped faster.
