Review (5/5): Good quality silicone travel bottles
These travel bottles come in a 4pk of different colors. They are a soft silicone material and are easy to fill and dispense. As long as you aren't trying to excessively squeeze out the contents of the bottle, there should be no problems with air flow to allow for the liquid to be dispensed easily. There is a see-through area on each bottle that allows the level of the liquid to be monitored. A set of labels are also supplied for better organization.
