It’s possible that it had been but I would say it was very highly unlikely. Back when an object would have had indulgences attached to it, one of the requirements was that it had to be sturdy (or I should maybe render it as “durable”). I can’t quite picture in my mind what a scroll box would look like but if it is significantly scroll, then I would say not.
In any event, objects enriched with indulgences lost their indulgences when bought and sold.
On the other hand, today one can gain the indulgence for the Stations of the Cross by pious reading or meditation on the passion for 15 minutes. If you use this object of piety and spent basically one minute with each of the stations, you could gain the indulgence.
One of the purposes of the reform by Blessed Paul VI was so that you did not have to rely on specially blessed religious articles or objects of piety that had been enriched with indulgences in order to gain the indulgence(s)…you could say the rosary on your fingers or use any sort of book or sacramental (or nothing) to meditate on the Stations of the Cross and gain the indulgence without a specially blessed and indulgenced religious article. The reform was meant to simplify and to extend the indulgences and, to an extent, to initiate a healthy reform.
