This is a plastic stand and test tubes that can stably hold six test tubes. There are 5 stands. There are 20 test tubes. I purchased these 7 years ago, but I only used them a few times and then stored them. Some of them have yellowed, possibly due to storage conditions, so please check the photos. - Color: White - Material: Plastic - Size: Holds 6 tubes - Design: Test tube stand Thank you for looking.
