KLUBIChemistry Gifts- Coffee Tumbler/Travel Mug 20oz - Gift Idea for Teachers, Biology, Nerd, Science Teacher, Biology, for Adults, Professor, Women, Men, Geek

I love the cup and it does hold some beverage warmth but the lids isn’t great. The lid doesn’t come apart and liquid gets inside the top seal part. After 1 week of use, the lid smells like mold. I can get cleaner inside via the vent hole but can’t really clean it. What a waste for the money I spent in it. ☹️Great gift for a science person like me, but get a different lid to make it last.

I bought this as a gift for my friend and she absolutely LOVES it. She decorated it with stickers that adhered quickly and cleanly and she says, “It literally keeps my coffee warm from 8 am to 3 pm, no joke.” It’s very sturdy, the lid fits very tightly so there’s no leakage ever if it gets knocked over. Would definitely buy again.

Our 12 year old son bought this with his own money to be a Christmas gift for his science teacher. He was so excited to do so. When it arrived, he looked it all over and figured out how it worked and said “it’s good! I’m happy with it 😁”. He can’t wait for Christmas to give it to her. We have no idea if she drinks coffee, but thought it was cute! LOL 😂

My niece is a Scientist. She liked this gift. I also gave her a set of DNA earings, necklace and ring.

I bought this for my daughters Science teacher for Teacher Appreciation and he loved it! It's such a cute phrase, the color is nice, like a light rust color and the cup and lid are very well made. I would definitely buy this again and also recommend as a gift or for personal use!
