30-Pack Sublimation Blank Coasters for Heat Press Printing - 3.93 Inch Round Rubber Cup Mats for DIY Crafts & Drinkware - Perfect for Home, Office, and Cafe Use

I’m a newbie at sublimation and this is actually only the 4th item I’ve sublimated. This was the most perfect turnout I’ve had so far! I used the suggestion of a previous review of 375 degrees for 40 seconds, medium pressure, kept all the print settings I had been using and Viola! It’s perfect! I couldn’t be more pleased!PerfectThese work great for sublimation! The color is vibrant, the coasters are sturdy and good quality! I sub at 375° for 40 seconds with about 44 pounds of pressure.These sub great. Good color transfer. Will probably buy more.I have used these for several different wedding gifts which turned out very nice.Make sure you use the recommended heat & time or they will curl.The sub went on so well. Will buy these again when stock is low for usThese feel and look beautiful when made with sublimation ink, however the neoprene soaks up any condensation from a cold drink and will leak through. I corrected this by using thin cork circles and adhering them to the bottom of the coasters and now it works well.I had ordered some before and I thought it was the same product, same seller, just the rounds without the squares as I purchased previously. It turned out different material, different heat time & quality if the sublimation was off slightly. Colors not as deep & rich, and had no sheen like the original order.No real complaints yes a few were dif thicker but for the most part same thickness I liked the rubber bottom when i pressed my first o e I got worried when I noticed it rolled but put my phone on it and once cooled it went perfectly flat so don't all and all I loved it and will be ordering againThis was a waste of money they shrunk when you applied heatI was disappointed in this , they are not the same thicknessSublime super bien!!!
