About this item

These snap-on stoppers provide maximum sealing for vials with a blow-back glass finish, which is a small ridge on the interior of the vials neck.

  • Not recommended for vials with a straight-walled finish

The blow-back feature is typically found in vials from North American manufacturers.

The snap-on stopper locks into the blow-back ridge, providing a tight seal and keeping the stopper from backing out.
