## Questions & Answers

**Q: Does it rattle like most multi-pens do? People commented that for the 3-color pen. I am wondering if that is the case for this 3+1 pen.**
A: No

**Q: Does this have an eraser on or in it? Since this is a mechanica pencil/pen... Thanks**
A: Yeah, you can twist off the cap and there's an eraser under it, it's not too large but it's definitely larger than the eraser's in any of the alpha gel or kuru toga lines.

**Q: Does it feel comfortable on your hands when writing as the Mitsubishi Select 3&1?**
A: Yes, of course but if you have bigger fingers I doubt. I think it is personal choice ...I enjoy writing since it has colors and pencil.The best is , look in a shop selling pen and you can make decision on buying. I am glad that I have one !

**Q: I realize the pen width is 0.7mm but does it write like a fine or medium point pen?**
A: Medium
