My new favorite tank top!

This tank is soo comfy! The color is very vibrant and fun! Fits true to size. I’ve only had my tank top for 2 days and I’ve already gotten compliments! The message “be kind” is very important right now with everything going on in the US and the world. I am recommending your shop to several friends who I know would love to support your cause!!

Very happy except...

I absolutely loved 3 of the shirts I received. All 4 of the shirts were very good quality and I was super happy with that. The only disappointment I had was that the 3x shirt’s colors were so light that you can hardly see the tye dye. We bought them to do a family picture and with three bold and bright and one hardly colored it didn’t really work out. But that is the nature of mystery and we took a gamble. All the shirts will still be worn and we would still purchase from here again.

Kindness Matters

I absolutely love my Be Kind Mystery Tee and the bonus sticker that came with it! I also love the fact that a part of the proceeds go towards teachers, as I am a preschool teacher! One of the things I teach my students everyday is the to be kind to others, because kindness matters. I can’t wait to order another Tee and a tank top!
