Diaper wipes have a fair amount of accessories. They have their own refillable bags.
Is it worth it to buy all these accessories? Well, sort of. Diaper wipes, like so many other refillable products, work on the razor model. The idea is to get a customer to buy a reusable razor, or in this case, a wipe warmer for your little one's behind, it can be pretty affordable. Assuming you need one; a family in a temperate environment needs a diaper warmer a lot less than someone who lives in say, Northern Canada. Likewise, a total homebody might not have much need for more than one basic diaper bag.
