CHaKOLAB Double-Layered Stainless Steel and Glass Cup, 620 ml
Guaranteed Safe Checkout
A glass cup wearing a steel coatSip from borosilicate glass, carry a 316 stainless steel shell.
This CHAKO LAB cup is a double wall glass tumbler made as two layers: a high borosilicate glass cup inside and a 316 stainless steel cup outside. The outer cup is rated at 620 ml (21 oz), and the glass cup you drink from holds 590 ml (20 oz) or 570 ml (19.3 oz) depending on the color. It suits anyone who wants to drink from glass but carry a cup with steel around it.
- Borosilicate glass you drink from
- 316 stainless steel outer cup
- Lid, straw and carry net included
- Four color choices
What each part does
Sip from glass
The layer holding your drink is high borosilicate glass. You get glass to drink from without a bare glass cup to carry around.
Carry in steel
An outer cup of 316 stainless steel wraps the glass, so it never rides unprotected in a tote or a backpack pocket.
Three extras inside
A lid, a straw and a carry net come with every cup, so nothing else is needed before the first fill.
How much it really holds
The spec photos list two numbers, and they measure different things. 620 ml (21 oz) is the outer steel cup. The glass cup inside is the part you fill, and it holds a little less.
That inner figure depends on the color. Dawn Blue Rose and Warm Sun Taro list 590 ml (20 oz), while Mint Cherry Talk lists 570 ml (19.3 oz). Either way it covers a tall iced latte or a water refill by your laptop.
The details
Is it the right cup for you
A good pick if
- You prefer drinking from glass but want steel on the outside
- You like getting the lid, straw and carry net together
- You want a color story that stands out on a desk
Look elsewhere if
- You need a published hot or cold hold time, which this cup does not list
- You want far more volume, where the START LAB straw tumbler is the bigger option
Short answers
Is this double wall glass tumbler glass or stainless steel?
Both. You drink from a high borosilicate glass cup, and a 316 stainless steel cup forms the outer layer. The CHAKO LAB dual-layer tumbler follows a similar glass and steel idea.
Does the CHAKO LAB cup come with a straw?
Yes. Each cup arrives with a lid, a straw and a carry net. If you would rather have a steel liner than glass, see the CHaKOLAB insulated straw cup.
How long will it keep my drink cold?
No tested hold time appears in the product data, so we will not quote one. What you do get is the double build, with glass and steel between your drink and your hand.
Which color holds the most?
Dawn Blue Rose and Warm Sun Taro, at 590 ml (20 oz) in the glass cup. Mint Cherry Talk holds 570 ml (19.3 oz), and Peach Nebula has no published inner figure yet, so ask us first if capacity decides it for you.
