4.5-Inch Long Borosilicate Glass Tube, 12 Mm Outer Diameter, 2 Mm Wall Thickness. Comes With A Cleaning Brush (7 Pieces)

Very nice, thick glass. Exactly what was described & they are very sturdy glass & easy to clean.

Came on time and the quality was great!!

These ones good with chore loaded and the other party favors don't have any chance, the hassle comes only with the best push cause they like some resistance to changeover being that they don't have the natural inner stop or lip like the common ones from bodega's, these are pri grade all the way very short learning curve get the 4" length and no worries when it comes to pushing chore, common hex end drill boys go through with ease as the above mentioned inner lip issue is absent from the field of play that's a game changer for sure sits easy to find push tool fighting to get clogged chore out, but really in the first place what a bonus when you don't have to crawl the walls and floors to find a suitable push tool, don't think twice, buy buy share if you want to have any future glass blowing tube shortage events I just share this review and say 'good buy' ! Straw quality: 110 Why did you pick this product vs others?: Trials

The product what it says, but was listed with another similar product. This one is not for MJ unless you are adding a screen.

Depending upon what you use them for they are doing exactly what I bought them for. Excellant
