I'm addicted to "lotions and potions" AND I adore miniatures, so you can imagine I'm addicted to travel size toiletries, as well as specialty bottles (Muji stores are fun for me in this area! I think Container store has some fun options, and I'm sure you can find any of it on amazon these days as well - though travel size toiletries can be hard to find higher end stuff, holiday gift sets are actually great places to find them - I look for good deals for myself, not as gifts ;-) I'm sure I have other ideas, so I'll let this percolate a little and come back if inspiration hits!
