Question: It looks like you can still see the image when the mug is cold. Is the black coating not that "thick" to cover the image?
Document: I thought the image would be on both side like other mugs I purchased. This is the first type of mug i designed the image/Quality of work was very good
Very friendly company to deal with, and the mug is nice enough. My only complaint was that the design shows through the black, even if the mug is not filled with hot liquid. Ruins the surprise a bit!I would recommend this, but only if you are not doing a black line design.
The sellers did not specify a photo size for inclusion - I simply got an e-mail a day later asking for a photo. Because of this I sent a photo with instructions for cropping to have it fit on the mug with minimal negative space. What I got was a photo that was not cropped and an image that was much smaller than it should have been.
For the mug and Idea and how it works, i would say it is good, but my problem came with the image, I asked for the image size they need and they said just send an image and they will handle it.My image was a QR code, so I sent the image and asked them to make sure that when it is printed on the mug, it will be scan-able with any QR reader on any mobile.
The color changing quality is great, the mug is a little smaller than your &#34;typical&#34; mug.WATCH OUT: I had 4 mugs made with custom pictures, one picture was in portrait and it only covered about a 1/4 of the mug. I highly recommend only using landscape orientation you can cover most of the mug
i will issue a full credit to your account.&#34; but I didn't receive any fund till now.I would say, if they only give you the size of the image that they print , that will make it a perfect gift for anyone. Sending the customer a sample before the final print is also a good idea.Overall, if there was no problems with the printing and sizing of the photo, I would have given them 5 stars for the quality and communication with customer.
What a beautiful cup. Christmas gift for my wife. I was contacted via email as to what picture I wanted on the cup. So I used a picture that my wife loves and emailed to them. I had to change the picture and they replied quickly, very pleasant. Make my purchase a enjoyable experience. Package arrived quickly and was protected well. The Cup is dark brown when it is cold. But turns white and shows the picture clearly when you put hot coffee or tea into it.
Returned customer, the mug was superbly performed according to my specifications. Couldn't be more happier! I would gladly recommend them to other users
Thermal mug, works exactly as promised. Print your favorite picture on the mug and watch it come alive when a warm liquid is poured inside! My nieces love this mug!
I was thrilled when my boyfriend told me he loves the mug. I can imagin his heart was slowly filled up with my tender loves, just as the mug was slowly filled up with hot waters and our pictures gradually showed up on the mug. I think its a wonderful gift to witness our love in the coming valentine's day.
Answer: You can see it a little bit but you have to look. These mugs really are awesome.
