Arthritic Hands
I'm an old optical scientist with arthritic hands. So, I have a little trouble grasping such a wine glass with such a broad base. No worries. I will let others use it and I will explain the differences between the band regions!
Good glass!
I’m enjoying the glass! It’s a great size and looks nice!

Murder of Crows Sticker
Beautiful Water Bottles
Beautiful design pattern, love the texture when touching the print on the water bottles, feels more like a 3D printed texture, and the bottle itself is with good quality.
Hearts Mean Love
I work for a biopharmaceutical company that is developing therapies for heart failure. When I saw the anatomical heart tote bag I had to have it! I also purchased several heart stickers for some of my colleagues. I love my purchases and I am excited to visit the store next time I am in the Redmond area!
