Recently I was invited by Smiley360 to sample Inkjoy pens and review them for free! My kids were so excited when our package of free sample pens arrived arrived. They immediately divided up the sample pens and we headed off to Walmart to use the gift card to get more. I cannot say enough good things about the Inkjoy line of pens. My oldest daughter and myself are left handed and finding pens we can use that do not end up all over our hands has never happened until now ! Not only do they not smudge but they fit comfortably without our hands cramping up. They write so smooth my 6 year old has been using them to color with as well. We will definitely be buying more in the future.
