While we've done a lot to make sure these infusers are sturdy enough to go places with you, they are still made of glass and require more careful handling than a metal bottle.
• Infusers don't like to be dropped, bonked, or toppled over on hard surfaces.
• When using these bottles with ice cubes, always add the liquid before dropping in the ice.
• After pouring in hot water, wait a few minutes before tightening the lid to prevent a vacuum from forming.

Core Sample Pencil Bag
Great tape
This was an impulse purchase and I don’t ever have high expectations for Washi, but this is high quality stuff.
As a paleo science geek I love all the archeology/paleo items! You can't find these anywhere else.

Love these
I'm a casual nerd and love geology. These pillows are a great nod to my rock obsession without being overly obvious. They just feel like abstract patterns. But they really fit the vibe of my apartment, match the color scheme I am going for, and are nicely well-made. I go for all cotton or plant-based materials if I am able and these being cotton sealed the deal for me. I love them. They're also the perfect size for throw pillows. Not too small, not overly large. I love them (I got two)!
