glass cup with bamboo lid

Primary materials are glass (several listings specify borosilicate glass) and bamboo for lids and bases. Some listings also include protective sleeves (silicone or neoprene) and occasional stainless‑steel components in inner lid parts or infusers.

Suitability varies by listing: some products are described for both hot and cold beverages, while others are listed for cold beverages only. Check each product’s description and care/temperature guidance to confirm whether it’s rated for hot liquids.

Many listings specify borosilicate glass. Protective options commonly include silicone or neoprene sleeves to insulate and protect the glass. Exact combinations vary by product, so check the listing for details.

Some items include stainless‑steel elements such as a stainless‑steel cap or inner lid components, and some offer removable stainless‑steel infusers for loose‑leaf tea.

Common capacities shown in listings include 16 oz, 20 oz, and about 22–22.6 oz (listed as 22 oz or 22.6 fl. oz.).

Many bamboo lids include silicone seals and are described as spill‑proof or leak‑proof to help keep drinks fresher and reduce leaks. Feature availability varies by listing.

Common extras include reusable straws (often glass), a straw‑cleaning brush, protective silicone sleeves, and a bamboo base. Some listings also include a removable stainless‑steel tea infuser.

Reported heights range roughly from 4.0 inches up to 9.8 inches, and widths range about 2.75 inches up to 4.0 inches. Exact dimensions depend on the model.
