Again this is the same for retail products. For example Tefal cookware has multiple factories, the good stuff is made in France but it also produces lower cost items in China.
Even within China there are different levels of manufacturer - for example there are factories that make stuff for top tier labels and others that are making stuff for Anako (Kmart) for 1% of the price.
Just looking at past QF amenity kits you can see varying levels of quality as the brand changed. I personally found the most recent Koskela series to be low quality, but it looks like their focus was on sustainability (apparently it was them who convinced QF to remove plastic tubes inside the kit); whereas brands who do make similar products (Kate Spade, RM Williams) have been a much higher quality.
