An awesome super wide bore top cap especially for taste connoisseurs, made from glass and stainless steel.

A superb RDA top cap constructed from a glass mouthpiece plugged onto a tough stainless steel base, it has a super wide bore giving oodles of vapour. Glass drip tips are recommended for a superior quality and clean tasting vape making this the ultimate top cap for taste connoisseurs. As it's made from stainless steel and glass, it's perfect for use with abrasive e-liquids which have been known to react with the plastics used in cheaper tops. This product is only suitable for 28.5mm rebuildable dripping atomisers (RDAs) which have a removable chuff or top cap, it replaces the entire top part of your compatible RDA including the drip tip. Easy to fit and supplied with a new single seal.
