6 Pcs 11 oz Sublimation Mug Glow in the Dark Sublimation Coffee Mugs Ceramic Straight Blank Mugs Sublimation Coffee Cups with 10 Sheet A4 Heat Transfer Paper 1 Roll Heat Tape for Crafting

These mugs were not completely covered with the glow in the dark coating. Zero stars for me.

These mugs did not come with any instructions. In addition, there aren't any instructions on the mug's Amazon page. If you're new to mug pressing, the buyer is left to figure out everything with ZERO assistance from the advertiser. There aren't any recommendations as to the temperature for the press, the amount of time to press, the amount of pressure to apply, and recommended designs/colors to use. When I sublimated it in my mug press, the heat resistant tape marks showed up in the glow-in-the-dark area. I ended up sublimating the mug at 340 degrees F for around 4.5 minutes. The mug does glow-in-the-dark as advertised. The reason for the three stars is the lack of instructions.

These are awesome coffee cups. They sublimated wonderfully. So fun to use. There was no flaws in these cups. I will be getting more of these for sure. They look really cool when they glow
