Recently i got this 4 in 1 pen that is actually a bubble pen with stamp. This 4-in-1 pen also has a roller stamp. I have seen other youtubers having a 5 in 1 pen which also includes light. My 4 in 1 pen actually doesn't have light but it can blow out cute bubbles especially when you're bored studying. So today i will be unboxing this 4-in-1 pen that is in my favorite color which is purple and show you the stamp, roller stamp, bubbles and also writing some words with it. This is definitely a unique stationery item that you should consider since it's so cheap too
