Hi Tiffney, The full size products do have much larger salt grains and it was because of the design of the travel pack that we had to use smaller grains of salt in the samples.
We have also had a few people say that the salt is slightly too large in the full size product so we have already taken steps to find a compromise and make the salt grains a size that will work in the Travel Pack but also in the full size products.
The new products will be available soon but in the meantime we would love to send you a complimentary full size product so you have the chance to compare that as well, please just email us at firstname.lastname@example.org
and we can get this arranged for you
