Since the 13mm round cosmetic flip-top closure is part of the tube, there are never any loose caps, no cap lead time and the cap is always correctly oriented to the print copy on the tube. There is also a snap-in feature for a bi-injection appearance. Available with a PCR body and cap, for a light-weight tube that is made with 70% less resin than the standard package. Suitable for samples, testers, and over-the-counter products.
