Laptop bags/ conference satchels (Cellardyke KY10)

Students, need a bag large enough for a laptop and books, with pouches for pens, notebooks, snacks etc? Might be suitable for cabin carry-on bags. I have a variety available. All in good/ very good condition. The first two photos are of a Dell laptop bag; the other four are conference satchels with the conference logo on them. Willing to deliver to St Andrews. Otherwise collect in Anstruther.
