Engineer Gifts for Men, Engineer Definition Tumbler, Engineering Gifts for Software Engineer, New Licensed Passer, 30 Oz Isulated Tumbler with Straw & Lid, Stainless Steel(Black)

This is a very nice tumbler! The tumbler arrived nicely packaged - the box was decorative and contained the tumbler, 2 lids, 2 straws (one straight and one bend), and cleaning brushes for the straws and the tumbler. The text was clearly printed on the tumbler. Please note that in the care instructions it states to only handwash it!It comes with two lids - one slides open, the other has a latch that opens and also contains a hole for the straw. The lids for the tumbler fit tightly. I would consider this tumbler spill-resistant; I would not call it spill-proof (in other words, the lids don't screw on tightly but they seal very well).The price is good, especially considering the size of the tumbler. It can hold up to 30 oz of liquid. I tested the tumbler by putting ice and water in it and letting it sit on my counter - after a couple of hours, the water was still icy cold. I did not test it with hot liquids yet. I also like that it is made of stainless steel.This tumbler is a great gift for the engineer in your life - the text is funny, yet spot-on.

Makes a nice gift for an engineer and pretty much sums up our sons experience in Chemical Engineering. 30 ounce capacity, it comes with two lids that have a strong seal, bendy and straight straws and cleaning brush. Decent build quality and fair priced. Recommended.
