Lock&Lock Boroseal, Borosilicate Glass
342009
As owners of Lock&Lock's plastic wear, the Borosilicate Glass is up to par with other containers;  however, the flowery lid pattern is highly undesirable as it blocks view of the contents.

These containers are better for storing solid foods or thicker liquids like soups or stews.  On the contrary,  thin fluids, like broth may seep out of the Boroseal lock.

Great for protecting fragile glasses, crystal and china for move

I bought two packages of these glass cabochons & are perfect for the trays I purchased. The package arrived with the cabochons wrapped very safely using bubble wrap & strong tape.

This is fantastic quality glass. True heat resistant glass with a beautiful finish. You will notice the quality as soon as you unwrap it. Very well built and the lid fits very nicely

Item was just as described and the free tweezers make this product a dream when using to replace glass. Love it!

The lock nuts are important, good job there. The blue silicon cups are soft, hold their shape, pick up anything that fits between the cups and holds tight !  Excellent product I would highly recommend.

Great lock, very solid.  As other reviewers mention, no screws for strike plate, but other than that very happy (see pic).

One caveat, description doesn't mention the minimum glass width.  Mine is 1/8",  and the lock screws weren't long enough to grip, so I had to add some pad (about 1/16") between the lock and glass to get it to grip well.  No big deal.

Was very excited to find a glass container set made with borosilicate glass.  However, no where on the packaging or instruction does it mentioned "borosilicate".  More concerning was the included glass care instruction sheet indicating that I shouldn't put these in the microwaves, ovens, or freezers.  I compared this set to the PopIt glass set I had purchased (at a higher price) and found that this VonShef set is not as clear as the PopIt; it has a slight greenish hue, which considering the included instruction I now dout if the product is indeed made of borosilicate glass.

Works exactly as advertised. Locks up good and tight to my Sony A-6000 and allows use of all of my Canon glass. I use both my EF and EF-S with full coupling through of the electronic features. A good investment if you own Canon glass.

These glasses were a fallback product when I discovered my newly purchased and allegedly frustration free Bodum Pavina double wall glasses had a major design flaw.  After shipping them back and ordering my Duos at another reviewer's suggestion, I'm very pleased with the decision.  The Duos may not share a glass thickness or design aesthetic with their Bodum alternatives but still have one thing going for them: they are entirely glass.  Pavina's latest glassware models use silicone plugs at the bottom to separate the two walls.  These easily come off in the dishwasher.  The Duos will never have this problem.

Duo glasses have a more sleek design than the alternatives leading to the thinner glass, but calling it thin is definitely an understatement  I'm not the most reckless with my glassware, but have never had a problem adding ice, or other potentially damaging things to these glasses.  They also clean up very nicely in the dishwasher.

The glass layers do exactly as advertised: insulate to prevent burned hands and condensation with cold drinks.  A shame Bodum decided to cut costs by using bottom plugs in their glass line, but it caused me to discover the Duos and I couldn't be happier now.

this lock is very simple to use.  We use it on a sliding glass window at an office and would buy this product again.

I have a sliding glass door with a dog door.  I cannot lock the door.  The door stoppers work perfectly.

High quality product as expected.  Highly recommended.

Love this black glass. Used for so many projects

Very impressed with the look and feel of these jars. They're unexpectedly light in weight, but since they are borosilicate glass (like Pyrex used to be), they should be sturdy and heat resistant. Just ordered another one.

Heavy glass with evident markings.  I order the clear glass so it does not have red and blue colors on it
