Whose pens?

I found a few pens inside Gordon's schoolbag just now. I dont think those are ours as i've never seen the brand around the house before. I've check with my father-in-law and he also says those are not his either. Then, my guess is he must have gotten them from school. I'll have to return those to the teacher tomorrow. Gordon cant write yet, even if he can, he will be using pencils and not pens, lol.
