cabin bag/luggage bag (Risinghurst OX3)

This luggage bag has the following dimensions: 60x39x20cm and should be fine for the occasional use or for storing items in the loft, just probably not suitable for very frequent travel, as the zip has a flaw at one end. However, if used at the opposite side, it will not affect its use. The bag has 2 wheels, instead of 4 which seems to be more common these days. The extendable handle works fine, just retracting it needs a little kick. Maybe WD40 would solve that issue.
