Type of writing instrument: Ballpoint pen Since this is a sold-out item, it's cute and I collected a lot of them, but I couldn't bring myself to use them. I haven't checked for ink problems.

Mickey Surf Jetstream and Dr. Grip are popular for their ease of writing. Everyone uses them at work and in their personal lives! They're cute, but if the color is the same as someone else's, you might not know which one is yours. Even if you have your name engraved, the colors can overlap! However, choosing your favorite ballpoint pen based on your mood for the day can boost your motivation! With limited editions, especially, they'll likely be returned to you if you leave them somewhere! I have dozens of pens, so I'm organizing them. I store them carefully at home, but thank you for your understanding. Motivation boost for those who like them! Please feel free to contact me. It's a very cute item! I also have other Liberty items for sale, so please take a look.
