When I bring my Heartbeat water bottle to the hospital where I work everybody is envious because they want one too. I send them your way. I fear the bottle will get stolen because it is so coveted. This bottle is not only cute and educational but also a high quality drinking vessel. It keeps beverages cool longer than others and it doesn’t sweat all over the desk when filled with ice.

I love this mug. The colors are vibrant and I adore all the little bugs on it. It also holds a surprising amount of beverage, which is excellent news for my coffee and tea habit. The shape is also perfect for warming your hands on a chilly day. I love how the design complements my floral and pollinator art in my office!
Tons of fun!
I was really excited to see journals that I would not have picked out on my own but immediately fell in love with when they arrived. I got six unique notebooks and I really appreciated the level of variety.
Perfect for planning out busy weeks. And its pretty too
