The Comsaf 6-pack is constructed from high-borosilicate glass with a wall thickness of approximately 2.3mm. This build provides excellent thermal stability, making the glass safe for temperatures ranging from -4°F to 300°F. This makes them a durable choice for kitchens where temperature fluctuations are common, such as near ovens or in cooler pantries.
The lids are made from Moso bamboo and are treated with a food-grade lacquer. This coating is designed to help prevent the wood from absorbing moisture or kitchen odors, addressing a common maintenance concern with natural wood storage. The triple-flange silicone rings are engineered to provide a secure airtight seal, which is helpful for maintaining the potency of ground herbs and spices.
Tests show that the suction-seal remains effective even when the jars are inverted, though keeping the glass rim dry ensures the gasket does not bind or slip during use.
If you are looking for a complete organizational overhaul with labels included, the 24 glass spice jars with bamboo lids and labels provides a larger scale solution with a similar aesthetic.
