I grew up being told that drinking outta mayo jars was socially unacceptable. Cuppow is making it socially responsible [and cost effective at 8-bucks] with their eco-friendly solution.
The Cuppow sippy lid fits onto most wide-mouthed canning jars. The lid is BPA free and biodegradable. The jars? You can get them anywhere...thrift stores, grocery stores, your grannies cupboard...anywhere. I'd say check your local thrift store, you're bound to spend less than a buck.
