A really good white 28 mm cap with seal (superior sealing against caps without seals) and warranty ring (sealing ring that is fitted over a notch on the bottle).
It is easy to remove the warranty ring and also use this sealing cap without sealing.
Liner sealing (Disc sealing) is tighter than edge sealing. This tamper-evident cap is excellent for 250, 500 and 1000 ML Pharma bottles and all plastic bottles with a 28 mm cap.
