I think one thing to note for Muk Jong shopping is not how much time for shipping haha I know u can't wait to get your hands on your brand new Muk Jong but remember quality is definitely important.
So if it takes longer is not much of a dilemma compared to if its good quality, I've always heard good things about Pagoda.
I had mine imported from China, previous to that picked up one from Wing Lam which suprisingly has held up to extensive practice.
So remember keep quality in mind, especially if you want it to hold up & last the years.
Be sure & take pics, haha a new muk jong to a Wing Chun practitioner is equivalant to a 16 year olds new car!
