EISCO 12PK Watch Glasses, 2.4" (6cm) - Cover Lids for Beakers & Flasks - Evaporation Dish - Polished with Ground Edges

So far so good! No complaints.

Thick enough to use without feeling they would crack and break with normal use. I love these and they come in handy often

These are beautiful and will serve their purpose well. They arrived packed nicely with each glass in a cellophane sleeve, stacked, wrapped in tissue paper in a little box. The shipper (Amazon) shipped them in a padded envelope which was not adequate, as the glass at the bottom of the box arrived shattered. The shipper may not have known that the contents of the tiny box was thin glass. It should have been boxed and kept from getting moved around.But aside from this, the product is nice. There are no scratches and the edges are smooth. I plan to use them for an art project .

It does what it's supposed to

Out of 12 glass lenses, one was broken. Handling in enroute, delivery problem I'm sure.

amazing quality for the price! Exactly what I was looking for!

All my watch glass covers arrived in perfect condition. I haven't noticed any chips or rough/sharp edges.

No problems. It is what it is. I would purchase again.

Para medir sustancia cumplen su cometido, pero el cristal se ve poco resistente, nada comparado con los Pyrex, no se si se especifica pero no creo que se puedan utilizar para calentar.

Para uso escolar esta perfecto
