Fit in my mug press, it was tight but i taped the design down well so it wouldn't shift when putting it in.I was happy with the product and my image showed up great. Did struggle with the size and it not fitting in my tumbler. Just had to finish up with the heat gun. Otherwise, would recommend for subbing onSaw other reviews that people used in Cricut mug press. I could not get it to fit. Was glad I had a back up convection oven I could use. I could force it in mug press with no design on it but no way once I put sublimation and one layer of parchment paper. The mug was great other than the miss leading description of fitting in Cricut mug press. ( I did try to sublimate the handle…. It didn’t take color very well)I normally don't leave reviews, but these fit wonderfully in the cricut mug press, the diameter is about the same size as a 15oz coffee cup, you can do wrap around designs or centered on each design on the sides.. It sublimates beautifully as well.. I plan on buying a ton more of these, I am extremely pleased with these.These cups are amazing for sublimation! I’m still learning how to get a full image on these but I’m making progress. These cups keep my drinks very cool for hours.Perfect for the Cricut mug press! Tight fit but turned out awesomeThese are great coffee tumblers, they sublimate perfect. Love them. I just ordered more and will continue working with this company. They have great customer service ,fast shipping and their products are just as shown on the site.
