We love to use our silicone and stainless steel straws along 20oz and 30oz reusable cups.  Rarely will you find us without this combo.  Each of our straws are sized to fit perfectly alongside 30 oz tumblers from Yeti, RTIC, BEAST, among many others.  Our silicone straws can easily be cut to a specific size with ordinary kitchen scissors.  Whether angled or straight, silicone or stainless you will be glad you updated that base plastic straw.S1S silicone straws are heat resistant; safe for hot or cold beverages and everything in between.  After reviewing multiple sizes and widths, we choose one that is slightly taller and wider straw than the average plastic straw; one that works extremely well for drinks of all textures including smoothies.SaveOneStraw stainless steel straws come straight or angled.   They are made of quality 18/8 stainless steel and if cared for properly will last a lifetime.  While our stainless steel straws can be cleaned under high temparatures, we do not recommend them for hot drinks as they can conduct heat.
