iSi presents flexible silicone mixing bowls and measuring cups! They have undulating rims that allow a pouring spout to be made when you need to pour liquids with precision, which eliminates the need for a funnel. In addition, they’re unbreakable, oven-proof, freezer-proof, food safe, and child friendly. If you like them, you can get them at Amazon.
