Glad to see that there's a place for people to ask direct questions of suppliers like ourselves here at CALMINI. We'll try to keep up with it as much as time permits. If you post a question and don't receive a timely response, please e-mail us at: sales@calmini.com or call us toll-free at: 800-345-3305. Thanks & regards, Steve Kramer, VP CALMINI Products Inc.
