These glitter pens are the perfect accessory for yourself or to give as a gift! They are glitter pens that are refillable, so not a one time use! The pens are Inkjoy gel 0.7mm, & they write so smoothly. The ink is black. These are handmade. There could be minor variations in colors due to computer/phone screen. There could also be minor adjustments as these are made to order, but will all be treated with the utmost care both in making & shipping. Thanks for supporting my small business!
