Why is　向けだ in this sentence and what does it mean.

Answer

向かう　normally means "to face toward (something)". But "向け” means "for" or "intended/designed for".

So you can translate it as follows:

These light-weight Christmas cards (found) here are (intended/designed) for (sending) abroad.

(my comment: since shipping cost is quite expensive in/from Japan, such cards are made).

I hope this helps.
