I love getting samples of products, especially face and skin stuff. Of course I am an organizer and don’t want to add clutter to my spaces. I am believer of bringing things in your house and USING them! Here are some suggestions from me:
If you have space on a counter, get a small basket/tray/cup/bowl and put the samples in there and USE them. Having them OUT is great way to not FORGET them.
Put in your gym bag and use them.
Take them with you when you travel. Especially for short trips, they are usually the right amount.
Trash any samples you don’t want. OR give away to someone you might know would like them!
