these plates come in a set of 8. effortless to refill water, tho may require some time. i let my teeth flosser do the water filling like a dumpling. might consider it a trip essentials to bring along with you!
These were awesome. I didn’t know what to expect considering some of the reviews. They are not going to fill 100%, but fill enough and the size of the opening is adequate. We used these while staying at a bed and breakfast and these helped us to keep us on track with our workouts. We would purchase again.
For the traveler who wants to stay in shape but avoid gyms. It is great product to carry when travelling and when you do not have access to fitness center. It is lightweight and easy to pack and carry.
