Thank you for the links. It looks like most of these sets are imports, and they are relatively expensive. I would say that most Filipino chess players would not be buying chess sets that cost P4,000, which would be about USD80. I'm surprised that there doesn't seem to be a Filipino chess set industry.
Any chess pieces and boards made in the Philippines?
Sort:
A set made from kamagong and yakal wood (hardwoods used in the Filipino Martial Arts) would be nice!
Sets like this are locally made and readily available online. Price ranges from USD 40-60 depending on the size and the sets are considered relatively upscale. The pieces are not weighted, but are heavy enough on their own. Vintage sets use actual kamagong for the Black pieces but I believe that for over 20 years, manufacturers just ebonize a cheaper wood.

There are also cheaper sets made with much lighter and softer woods. These would cost around USD 10 max.

These days, with the global economy, it's relatively easy to import sets (plastic or wood) and equipment and many Filipinos do so.
Thank you! There are some nice sets there. But most of the ones they had seem to be made abroad. I did not see any that were advertised as locally made. I am looking for a set made of wood, with annotation along the sides. The set I use now for my studies is 9.5 inches by 9.5 inches, which is very comfortable. I would prefer something not much larger than that, maybe 12 inches.
My wife is going to the Phils in a few months, and I hope she can bring a chess set back for me. Maybe one of my nieces or nephews can buy it and have it waiting for her when she arrives. 
I would prefer a locally made one--we look for Filipino products whenever we can.

The first link I posted offers locally made sets in various sizes and I think the “Small” size would fit your 12-inch requirement. Look at pic 3/3 for the sizes.
However I don’t believe notations come standard on Filipino boards - I can’t recall seeing any such.
Aside from the links I posted, there are also individual craftsmen still making boards and sets, both in traditional and unconventional styles. Several can be found on FB. Please do a FB search using “narra chessboard” and “narra chess set”.
Good luck with the acquisitions!
My wife bought two chess sets for me when she was in the Philippines in April and May. At the store they tried to sell her a set made in China, but she insisted on a Filipino made set.
The two she bought are what we would call bargain sets in the US. Each one cost 3-4 dollars. Not great quality and no annotation along the sides, but they are wood and I love them because they are gifts from my precious wife.
One is from a place called Lual Woodcraft in Cavinti, Laguna. The other is from Manito's Woodcraft in Sampaloc, Quezon. I will post pictures later.

this kind? 
I've done some Google searching, but the only things I've found related to chess sets in the Philippines are very expensive antique sets sold in the US. Where do Filipino chess players buy their pieces and boards? Are any made locally, or are most of them imported?
A while back I saw a news story about a young man in the Philippines who started a company that makes absolutely beautiful bicycles from bamboo. It occurred to me that it should be possible to make chess sets from bamboo. Its a material the country has a lot of.
