Handy ashtray for the lone cigar smoker. Measures 7" long, 1/4" at widest and 2 1/4" tall. Single rest is 3/4" wide and level. Made of colorless solid molded glass. Dark areas on glass in images is a reflection.  Has some tiny trapped air bubbles within the glass and a ring of bottom-wear on the base (from years of surface contact).  Maker and age unknown.
