Review (3/5): Decent, but disappointed
I have ordered these several times now, and they do work out okay. You need to make sure to have everything correctly sized/at the right resolution and set to A4 paper size before printing so that the images turn out well. You also need to apply the adhesive sheets with a lot of care and patience to ensure there are no bubbles or wrinkles.
When applied, the tattoos are shiny, as most temporary tattoos are. This can be fixed with a dusting of baby powder or matte makeup powder. The only issue I've had is that the edges tend to peel quite a bit if you place the tattoo near a joint/bending part, like your elbow/inner elbow, knee, etc. Any place that moves a lot. But as long as you put them somewhere that doesn't move so much, they last several days as long as you don't pick at them or fiddle with them.
My biggest complaint is that the last time I ordered these, I went ahead and printed my images, and then as soon as I went to apply the adhesive sheets (which is quite a process and definitely made easier with two people and a good amount of patience, if you don't want any bubbles), I found that every single one of my adhesive sheets were defective. I've attached photos so you can see what I'm talking about.
In between the adhesive layer and the yellow backing paper (which you peel apart to apply to the printed designs), there were tons of little black specks/dirt. They were stuck in the adhesive, which obviously rendered them useless, seeing as I don't want black flecks all over my printed tattoo designs. I am super disappointed in this considering how expensive this paper is, but I don't think I can get a return since I already printed on the sheets. I just can't believe that something of this price would have such a flaw in the quality, and despite having success with these previously, now I'm hesitant to buy again.
