I've loved every product I've purchased from Beaducation...except this one. Since it's not a Beaducation-made product I don't feel too badly for leaving this negative review.
I had high hopes for the product when it made its debut last month. Since I've always used either an industrial sharpie or metal paint markers to darken my impressions. It worked fine, but I was never sure that I was using the best material for the job. When this came out I thought "Wow! This has got to be IT!"
What a disappointment. :( I followed the instructions precisely on several different pieces with several different types of metal from 20g to 18g. The ink doesn't stick. Period.
Even if your impressions are deep, the ink wipes right off after you wait the 10 seconds as instructed. And even if you leave it on overnight as I did to try to test it, it still comes off.
If it does that to my work when it's on the bench, it's going to do that when my customers are wearing it.
I'm bummed I wasted $8 on this. I'll stick to sharpies and paint markers.
