thermal cups

Thermal cups in this selection are available in common volumes: 11 oz, 14 oz, 18 oz, 30 oz, and 40 oz.

Thermal cups commonly use vacuum insulation and double-wall (dual-wall) construction; some models also feature a copper-coated inner wall for extra insulation.

Most thermal cups have stainless steel bodies (often specified as 18/8 or recycled 18/8). Lids and caps are commonly plastic or copolyester, and some listings include silicone straws or silicone bases. Several items also note BPA-free construction.
