I purchased the bottle shown in my initial post back in Feb of 2014 and the bottle is still 2/3rds full... So at least for me, a 4oz bottle of this balm ( just a nickel-sized dab is sufficient) lasts quite a while.
Update-had my first go with a sampler this morning. I reviewed it at SOTD, but one thing I forgot to mention is I really like the smoothness it provides. This was the 1911, but I bet they all give the same smoothness.
Along with you, I like the Heartwood and 1907. The first 3 samplers I will use are those two and the 1911. Tried the 1911 this morning and was very impressed at the way it softened my face. But today was quite warm, whereas tomorrow will be colder so it may make it feel softer.
