uni STYLE FIT 3-Color Holder, No Clip Metallic Pink, 1 piece Oil-based JETSTREAM Refill 0.7mm Red, 7 pieces Stored for a long time. I have tested them and they write without problems, but since it's impossible to test all of them, returns and refunds are not accepted if some don't write. The holder also has minor scratches due to home storage. Please understand the above points before purchasing. Please refrain from purchasing if you are sensitive to these issues.
