Double wall, cold all day. Printed and packed by hand in love.
An insulated tumbler is two stainless steel walls with the air pumped out from between them. That vacuum is the entire mechanism: heat cannot conduct across a vacuum, so the drink stays at its temperature and the outside surface stays at room temperature.
Every size in this collection uses the same wall construction. What changes is capacity, base diameter, and lid type, which is what you are actually choosing between.
Hand wash the body, and pull the lid gasket weekly, which is where every insulated cup eventually develops an odor. Insulated tumblers are the most given item in this shop for teachers, nurses, and graduations. 10% of every purchase is donated to a Christian ministry, mission, charity or non-profit. You are helping the Kingdom of Heaven with every purchase.
Air is removed from between two stainless walls. Heat cannot conduct across a vacuum, so the drink holds its temperature and the outside stays dry.
20 to 24 hours with a closed lid at room temperature. Prechilling the tumbler before filling adds noticeably.
Hand wash the body to protect the powder coat and the design. Lids and straws are top-rack safe.
The lid gasket, not the body. Pull it out weekly and wash it separately.
No. That is the practical advantage of a vacuum wall over a single-wall or foam-insulated cup.
12oz for a small coffee, 20oz for most people, 30oz for all-day water, 40oz only if you have somewhere to set it down.
Every bottle funds a well.
