Are the silicon sleeves dishwasher safe? How does one contact the maker direct?

Hi there. To make sure you clean the sleeves well, you can first remove them and wash them by hand with detergent. To contact us, you can send emails to: SophiaxjUS@163.com

Are these 100% silicone? Do they pass the "pinch test?" Or are there plastic fillers? Thank you!

Not sure I understand. The bands stretch and stay on nice and tight. I send them thru the dishwasher and they're fine. My issue isn't the bands. The cup taste like a cheap set of eating utensils. You know that metalish tasting whang? My kids don't seem to mind tho. They fir their hands well and the bands give a toddler a good grip.

Can you put hot coffee in these?

I would say no...because there is no insulation.
