100 Chemistry Lab Test Tubes+Tapered Corks

I purchased three sizes of test tubes with corks to use as sample vessels at my winery & restaurant. A creative idea we came up with to serve flights and samplers. When I put in my order I was a bit concerned that the glass would be thin and easily breakable. Well, I'm happy to report that the test tube glass is thicker than any I've ever used and is crystal clear, making a great visual for my wines! Excellent customer service and super fast delivery with shipping notification. The high quality box and packaging shows the company actually cares. I am beyond satisfied, unlike purchases I've made at Amazon where items come too often broken, dented or not as described. No more ordering from them or businesses like them for me. Indigo Instruments is on my rolodex of suppliers moving forward.
