Yep...clothes are good (use them to cushion delicate stuff too...like framed pictures).
Also, curtains and blinds. Handy to have.

All those little bits and pieces from your kitchen drawers.

Tools, as quality is usually rubbish in the Phils, and all will be to buy again. Small garden tools also.

Same goes for electrical connectors, computer leads, etc. Don't take up much space, but handy to have, and quality better from here.

Even consider some small cans of paint, rather than throwing out, as choice is limited in the Phils.

The boxes they send you are normally very thick cardboard, which are fine, but cover them totally in plastic parcel tape, so that they never get wet.
