I was so excited to receive the Forever Placers and try all of the different tips. I got really good with the single placer and triple plastic placer that came with my kit, but I was ready to try something nicer, so I ordered these. There is a bit of a learning curve. I’ve done a few paintings now and I’m starting to get good with them. My advice is start slow. I got good with the triple and 6 placer and just yesterday started working with the ten. I love the gem straightener as well and the curved single placer is nice. It may take you a little time to get the hang of it, but I think that the Forever Placers and a good pen is worth the investment.
