HI! I get mine at National Art Craft. The more you buy the cheaper they are. They have them in white, black, and brown. Clip in, snap in, high profile, and low profile. 6 feet and longer. I get my silicone tipped bulbs from there too. I love to purchase things from the same place and save on shipping. They have great customer service too! www.nationalartcraft.com Corey Midwest Silicone Molds/Scents N' Such www.scents-n-such.com
