Tumblers

These are my two Omega travel tumblers, which I use for brewing my coffee.  The green one is in my office; while, the violet at home:

A piece cost P300 only.  The capacity is 400 ml, with a heat retention of 6 hours.  They are made of stainless steel with polypropylene cover.

I checked also the other brands, such as Emsa, Tiger, and Zojirushi with heat retention of 24 hours..  Better, all right; but, they cost more than a thousand bucks

For my purpose, the Omega tumblers can do the job.  This is where I measure and store the 200 ml hot water for a few moments before pouring over the coffee grounds.
