Drink Protection Cap,drink covers for alcohol protection，Disposable foil airtight lid stickers for wine glasses and tumblers. Easy to carry, night out, bar, party, (100 Pack)

I got roofied a few months ago, even though I was holding my drink, and it was horrible. I bought these to protect my drink. I only set it down to take the pic. It works great! Plus no more spilling my drink on the dance floor.FYi the top of your glass must be totally dry when you put it on. I use a cocktail napkin and go over it several times, and then apply the sticker.Women always want to know where I got it. I carry extras to share.

Could come in different sizes and could be more flexible. Wrinkles terribly when shaping on a smaller glass and looks tacky

Good for regular size cups

These are grey!! My niece went to college for the first time this year and I purchased these for her and all of her roommates and friends! She says they work very well! They are easy to carry and she said she always brings a few extras for any one who might need one.

These covers are amazing! They're easy to place on your cup and you can tell if it's been tampered with because the cover will be wrinkled on the end where someone tried or opened your drink. I like that once you fully remove the cover from your drink there"s no sticky adhesive so great if using them around the house. These are also good to use if your in a hurry, but need to protect your drink from spills (coffee, juice, tea, etc). They're also great if you like to keep a cup of water near your bed at night these will keep dust and bugs out of your drink. And finally I like that you can insert a straw in to them as well -- so cool!

Decent quality for the price.

First off, they are very classy looking. They seal nicely. I even turned the cup upside down and it took a few minutes before anything leaked out. I have meetings at my house, it helps to prevent leaving drinks around and other people mistaking drinking from them.

Got these for my daughter heading off to college. They are textured metallic stickers with an image of a martini glass on them, which, according to my daughter, makes them look cool. They are a thick-ish aluminum, and the outer 1/4" of the edge of the sticker has the adhesive that anchors it to the outside of the glass. When we tried to remove the sticker (as if to sneak drugs into her glass), the sticker was resistant to being removed and it crinkled, so it was somewhat obvious it had been tampered with. My daughter likes that the stickers can fit into the smallest purse. She folded them into fourths and put them in her purse, then unfolded them and tried them on a glass, and they were intact without tears even after being folded in the purse. She preferred the stickers to the cloth caps that look like scunchies. Those seemed easier to tamper with than the sticker. Nothing is foolproof for safety, but education about spiking drinks, personal awareness, combined with the stickers, is at least a defensive move. I got the 100 pack so she can share with friends.
