I have used similar in the past. The difference is this one comes with a velvety cover that can be removed to wash. It also comes with a really cute travel bag! I love this set and it's the best I have seen.
It has a WONDERFUL light lavender scent that becomes more fragrant after heating but not overwhelming. It is a relaxing scent. It fits nicely on my stomach and my neck and it comes in an attractive box that is good for gifting.
To use is super easy. I popped it in the microwave for 90 seconds. The warmth sticks around for about 30 minutes. Slowly dissipating as time goes on. Love that is designed in New York City and it is 100% natural and eco friendly.
