Core Sample 500 mL Steel Bottle

Stella v.d.H.

Practical and wonderful

For me, as a paleontology buff, the design hit home. Delivery was fast.
It feels like a very good quality bottle. Not flimsy at all. The insulation is excellent. I love the design and the texture of it. This will serve me for years.
