Contents of a box

Hi,

If a muktzeh item is left atop a container before Shabbat, the container itself becomes muktzeh under the laws of "basis" we have defined in earlier emails. However, the contents of the container are not muktzeh.

Therefore, if the container could be emptied without opening a lid on top (on which the muktzeh object rested when Shabbat began) and without moving the container, then the contents could be used.

(Shemirat Shabbat K'Hilchatah 20:58)

Have a great day,
Mordechai
