can you buy the blocks individually or must you buy the case

buy 1 block
Asked by: ac
Normally, any product stocked in the store could be purchased as individual pieces. Anything ordered from the plant needs to be purchased in even case quantities.

Do these bricks offer privacy if they are used on an exterior wall in a bathroom?

In the ThinLine Series Glass Blocks are available in the Decora pattern (medium privacy), IceScapes pattern (medium to maximum privacy) and the Delphi patern (maximum privacy).

If these blocks aren't available to look at in the store, is it possible to order a box, and return it if it isn't what's needed? Thanks.

Asked by: Mado
If proiduct is returned, there is usually a restocking charge. Although ThinLine Series are not normally stocked, the pattern would be the same as the Decora 4" blocks stocked in the stores.

Rated 5 out of 5 by from Calling all Women! Finally a product that is truly female friendly. I put together 3 short sections (floor to ceiling) at my business using the thinline 4x8x3, 6x8x3, & 8x8x3 sizes, and finished feeling like I was all that! They are sparkling and beautiful, compliments galore from everyone that sees my project. Rest assured I let 'em know where I got it and how fairly uncomplicated it was to do. Glass worker for hire!!
