Ill be a juinor in High school and I want something wthat I'll get alot of use out of. I was thinking maybe a Damier Pocket Agenda. Does anyone have this item? If so can someone show me the inside of it and tell me what they use it for? Id most likely jot down my homework or something to remember. Any other suggestions on items you think i should purchase would be great! I'd like to keep it under a $300 limit. Thank you in advance!
