Third-party store in the Philippines for apple pencil engraving after it was already purchased.

Would like to ask for stores in the Philippines where I can have the apple pencil engraved. The apple pencil was already purchased and I have been using it for more than a year now. I already searched the net and found none related to my query. Also asked powermac center, beyondthebox and Apple. Apple recommended searching for third-party stores that do engraving. Could you suggest stores in the Philippines where I could have my apple pencil engraved?
