- 300 ml (10.1 oz) single-drink size
- Twist seal closes without a lid
- Straw-friendly silicone top
- Seven blue character prints

Why skip the snap-on lid
A cup with a separate lid
- The lid ends up in one place and the cup in another
- Snap tabs loosen with daily use
- A lid that pops off in a bag means a wet bag
The twist-seal cup
- The silicone seal stays part of the cup, so nothing goes missing
- Rotate it closed before the cup goes in your bag
- Rotate it back to sip, or slide a straw in
Pick the face on your cup
Animal prints
Penguin, lion and panda, each on the same blue cup. Easy to spot in a lunch box or on a crowded desk.
Winter prints
Santa and elk for a stocking filler that keeps getting used well after the holidays.
Smiley and eye
The smiley face is the simplest of the set. The seventh design is listed as an eye print, so check the photos to see it before you choose.

Twist it shut before it goes in the bag
The seal stops spills only when it is turned closed. The first time, fill it with water, close it and tip it over the sink so you know how far to turn.

The details
Is this the right cup for you
A good pick if you
- Keep losing lids or breaking snap tabs
- Want a small cup for a commute or a school bag
- Like to drink through a straw
Look elsewhere if you
- Need a big bottle for a full day, since this one holds a single drink
- Looking to keep coffee hot for hours? The listing makes no insulation claim, but the Snoopy insulated coffee mug is made for that
Answered plainly
Is a lidless cup really a leak proof travel mug?
Yes, once the seal is twisted closed. The silicone top rotates to shut the opening, and that is what keeps it spill-proof on the move. Leave it open and it behaves like any open cup.
How much does it hold?
It holds 300 ml, about 10.1 oz. That is one regular coffee or a small water refill, sized for a trip rather than a whole day.
Can I drink from it with a straw?
Yes, the top is straw-friendly. If you want a version listed with a straw, see the lidless silicone coffee mug with straw or the reusable travel coffee cup with straw.
Does it keep drinks hot?
It is not sold as an insulated mug, so a hot drink cools the way it would in a regular cup. Drink it on the way.
