I love this durable travel mug! The printing is flawless, & the colors are vibrant! The mug cover pulls off & presses on easily (it is not a screw top), & the rubber ring inside the cover creates a very tight, secure seal between cover & mug. I have had no leak issues at all. I accidentally knocked the mug over on its side (full of coffee), & didn’t lose a single drip of it! The inside is a stainless steel finish, & keeps coffee hot for quite some time. This really is a great travel mug!
