Item is not sent out as described
This item is not sent out as described. I only received 1 pack, instead of 6. Tried to explain that 5 were missing and received a replacement order of 1 pack. Very overpriced for a single pack.

Premium Cotton Rounds
These are great cotton rounds, because they don't shed. I use them on my eyes twice a day, morning and night.

Good for your teeth
These are great tasting and good for your teeth. Was recommended by my dentist after lifesavers damaged my teeth. A little spendy but worth it if you enjoy hard candy.

Tasty sugar free treat!
My sister is about to begin chemotherapy and her oncologist shared that hard sugar free candies that contain xylitol would be very helpful with the dry mouth chemo is likely to create. I ordered these for her and she says they are delicious! Good natural fruit flavor…tasty for anyone who wants a better quality, healthier (in moderation) sweet treat now and then. Arrived promptly and container was undamaged.
