Karter Scientific 50 Piece Assorted Color Plastic Test Tube Set with Caps and

Traen tapa vienen en varios colores , tal como en la descripción pensé que serían un poco más grandes pero cumplen su función, los utilizaré para shots en una fiesta de 15 años.

only thing is, you need to make a tiny slit with a knife on the lids/caps so they secure tightly and won’t pop off…once that is done, they can be used over and over again

I ordered several items from this seller and was happy with all of them. Caps stay on, nothing was broken. Rack is flimsy, but okay if you use tape reinforcement and don't put pressure on it. Meant to be a display item or used to help fill the tubes but don't plan on reusing a lot. Tubes themselves are quality plastic, but don't drop on the floor or squeeze too hard - like most novelty test tube items, they will break or crack if misused. Great price for what they are - fun for a party, for drinks, candy or filling with sugars, etc.

Great product! They are the perfect size for the shot of your choice and travel great in a cooler on the river (not glass so perfectly legal). You'll be surprised how many friends you make! The caps are NOT defective, it is an air-tight tube. When you compress the air inside it wants to push back. The upside down push on a counter top works like a champ. I'm getting ready to place my 3rd order in about as many years, "buying speaks louder than words"!

Love them but I wish the holder was waterproof and more sturdy.
