  • Item Category: Entertainment
  • Owner/Dealer: Bigdaddy50
As you can see in the pic, I measured the smallest to be 11mm and the largest to be 15mm. These are universal that should fit either plastic or glass tubes. It has ridges around the top to make it easier to put in and take out of the tube. If you look at the pic it has the hollow top. I am selling them in bags of 250 caps per bag. These are new and never used. **Pay at door or paypal and shipping is available** **Please email me with your location and qty. wanted and I will let you know the shipping cost
