Review on Sursip Changing Reusable Straws Tumblers by Scott Rao

I run an Etsy business featuring these. I've ordered a lot in the past. However, on this last order I received 4 cups instead of 5. I contacted Revain who quickly resolved the issue by giving me a refund and sending me an additional set to make up the difference. But I still only received 4 cups instead of 5 as stated in every set I received. Just note that you may not get 5 cups. Good quality, holds up well.
