From a supplier listing, a set like this usually has these features:

• Made from high borosilicate glass (known for better thermal shock resistance vs regular glass) 

• Bamboo lids / bamboo covers, often with silicone gaskets to form airtight seals Sometimes includes a bamboo stand (wooden rack) to hold the jars in one place or in a tiered manner 

• Used for household food storage (spices, nuts, grains, etc.) Dimensions in one example: ~17.5 × 11.1 × 14 cm (for one jar) in that set

• Transparency (you can see what’s inside)

• Better durability / heat resistance (thanks to borosilicate glass)

• Airtight seal keeps contents fresh

• Aesthetic look (glass + bamboo is trendy / “natural” style)

• Space organization (stand helps keep jars organized)

Drawbacks / cautions:

• Bamboo / wood components might warp or degrade over time if exposed to moisture

• Need to ensure the silicone gasket remains intact for airtightness

• The stand must be stable (if jars are heavy)

• Check if glass parts are dishwasher safe (sometimes lids are hand-wash only)

• Shipping / cost could be higher (glass + wood parts are heavier / delicate)
