XXX WJPOPHN Tumbler Adapter Stanley 40oz Cirkul Cap Fit

WJPOPHN Tumbler Adapter — Stanley 40oz to Cirkul Cap

Sip Cirkul-flavored water from your Stanley 40oz. WJPOPHN tumbler adapter screws onto the Cirkul flavor-cartridge cap and threads into the Stanley Quencher 40oz mouth. Keep the tumbler you love and the flavor cartridges you bought — no separate Cirkul bottle, no leaks, just a single shim that bridges the two.

Imagine sitting in afternoon meetings staring at plain ice water while your gym bag has six Cirkul cartridges going to waste at home. Twist the adapter on, drop in a strawberry-mint cartridge, and your $40 Stanley is suddenly a flavored-hydration machine without buying another bottle.
