I like their figures, but the ones with bayonets are just wasting everyone's time, as they are too weak to survive the trip in a post van. You can guarantee that several out of each pack will have broken off upon arrival, in my experience.
I have not experienced any breakages with Woodbine figures other than bayonets, and luckily for you the Gurkha figures don't come with fixed bayonets. So I reckon you will be fine.
