Just pipping in here. Not sure even sure it’s possible. But check to see if there is a Thai community near you and ask how they send items to Thailand.
It is so refreshing to see that someone is asking for advice/assistance and to see some of the replies are useless to say the least. Humorous replies are fine but the plain unhelpful are just crazy. Some people have nothing better to do than try to discourage people and be negative.
