She was devastated to misplace the pen and despite searching I couldn’t locate it. I came across this multipack for a very reasonable price. They’re absolutely perfect! The different “colours” are only of the cases - the ink itself is all the same colour (invisible when it comes out and shows up kind of bluey grey when you shine the attached blue light on it). Little one loves writing on not only her notebook but also on her hands, arms and mine 😂 So much entertainment value for such a low cost. She’s chosen a few of the different colours for herself and I’ve popped the rest away to stick in with birthday presents or keep as party favours. Can’t speak to longevity but at the is price my expectations are realistic. The ink flows well, the blue light is initially activated by removing a little cardboard strip to enable the battery and they’re exactly what I’d hoped for. Review: Excellent product and service - A great pack of party bag fillers, all excellent quality and well packaged. I had to return them as the party venue ended up giving us party favours, but the returns process for this item was extremely excellent! Thank you, would buy again.
