I make custom cups and provide these with my cups, customers love them and so do I!

Love them. They make cold drinks more refreshing since they get cold in ice.The only flaw was that I didn't receive long straight staws.

This is a durable product! They go great in Yeti and Magellan vacuum thermos cups, and do not seem to melt ice quicker. Be prepared - they are cold when sitting in ice! They come with a very nice brush for cleaning out. A good product at a good price point. Would be great if they came in a cloth bag.

Works good. What else is there to say, it’s a straw.
