This listing is for the set... (2) holders and (1) wooden towel holder as pictured. The holders are 2 1/2" x 4 1/2" x 4 1/2" . When assembled the rack is 16" inside to inside and approximately 20" to the outside of each holder. There is no name one the bases, but all the other salvaged pieces from the 60's bathroom were stamped Tilecrest made in U.S.A. and also had the round grout hole.
CONDITION:
I see no cracks or chips on the visible blue portions and the grouting bases cleaned up very well. There is very little residual grout on the mounting side of the base. I don't see any reason why these couldn't be reused in your project. See photos.
Check my other listings as I have some other matching blue tile items and tile.
GUARANTEE
My guarantee to you on used condition items...I will only invest in, purchase, and sell used items that I would want to use myself. In other words if the outside or inside is "nasty" I wont buy it to sell. So... I try to take detailed photos, I also try to capture any cosmetic flaws that I see upon further inspection. See photos and ask if you have any questions before you agree to the purchase.

I usually begin processing your item the day of purchase M-F and ship it to USPS the following business day. Purchases made on Fridays will sometimes be shipped to USPS on Saturdays. Positive feedback will be left for you once the item is out of my hands and in USPS possession. PLEASE leave feedback for me when you receive your purchase. Thanks for your business!
