I’ve never tried 3D-printed lashes before, didn’t even know it was a “thing”. Made me feel on the cutting edge of the beauty technology as a consumer, super fun. The clusters aren’t as lifelike as some of the others on the market due to the material, but they are quite pretty on, fairly comfy and not too heavy to wear. They fit well; I only used 4 out of 5 clusters for my smallish eyes. I’m not sure that the clusters would be reusable though, since they shed a few “hair” even as I pulled them off the tray... So that diminishes the value a bit for me, as the durability is iffy. The adhesive is decent, they give you mascara wand type applicator for the lashes side (“you”) and a tiny paintbrush applicator for the clusters (“TAD”), both are black and I imagine the same formula with PAO of 6 months. The sealer is your regular clear sealer that knocks down the residual glue tackiness, PAO there is 3 months. I brushed it on the lash tweezers, before clamping my natural lashes together with clusters. The issue I ran into there is the sealer dried fast on the tool and then my tweezers ended up sticking to the clusters. And then it also made the clusters clump up and start looking chunky. Then I had to quickly reach for my trusty lash comb, trying to remedy the situation. I made it work. Also, as much as I tried to press and fuse the transitions between clusters, I can still see some clusters forming a small mountain fold in between, which tells me that the bands made out of this material aren’t super flexible and don’t fully conform to the shape of the lid they are glued to. So a few small quirks here and there. This is still new technology, so I bet we’ll be seeing updates and improvements. Anyway, sorry for the novel. TL;DR: at the end of the application, the result was beautiful. Perhaps more dramatic than what I’d consider “natural”, but very feminine and striking. Worth the extra hassle. And I feel so high-tech sporting these 3D-printed lashes!
