Review (3/5): You get what you pay for
These plates are just cheaper (price-wise and quality) versions of Konad plates. You get 21 plates for about $18, and shipping is free, so that's quite an irresistible deal, but I have to say, these plates CANNOT compare to the Konad plates.
First of all, there is no safety backing on the plates, as many people have written already; the plates are very thin, and can be very sharp. I resorted to pasting the plates to index cards so it's less likely to slice into my fingers, and to prevent the plates from scratching each other.
Secondly, the designs of the plates are not as intricate and well done as the Konad plates. I have a bunch of Konad plates, and the BM designs definitely don't come close. The BM designs are not as detailed, and just are not as "pretty" as the Konad designs (but of course, you get what you pay for). Also, some of the plates I got, seems like there were manufacturing flaws. The designs on the plates appear smeared, or smudged, and when I tried to stamp them, the images do not transfer properly, if at all.
Thridly, the full nail designs don't actually fit on your whole nail (unless you have really small hands, or are a child). I learned that if I'm very precise on how I stamp, I can get away with stamping the "full nail" designs from my index to my pinky. Thumb is definitely out of the question, lest you end up with a half stamped thumb, or you're good enough to stamp in two halves (you have to really match up the designs). I've never had this problem with Konad designs.
Fourthly, some of my plates arrived with water and rust stains. I don't understand how this happens, since there is a thin Saran type film ontop the plates when you first get them. This must mean that the plates have somehow gotten wet during manufacturing process, but before the packaging process. This doens't interfere with the stamping process, but I just find it annoying to have rust and water marks on my plates.
Overall, these plates are dirt cheap (under a dollar for each plate), compared to Konad which are between $4-7 per plate, but you get what you pay for, and Bundle Monster plates definitely do NOT compare to the quality of Konad's.
