Cupture Crystal Click & Seal Shake Tumbler Cup for Hot or Cold Drinks - 22 oz (Clear Diamond)

Q: Is it dishwasher safe?

It is dishwasher safe on the top rack only. I've been really pleased with this tumbler. I like that it can be used with or without the straw.

Q: how long is the straw in inches?

The straw is exactly 10.5" long.......(10 1/2" ). The diameter of straw is 5/8". This is the only problem I have with this tumbler. Wish they had smaller diameter straws. But I'll tell you, I use this every single night. I fill it up with ice then add water and the ice is still there many hours later just about the entire night!!
