Isabella is white at its brightest — clean, luminous, and lit through with the softest shimmer, like light on satin. She’s the LUXE piece that disappears into any palette and elevates it at the same time, paired just as easily with morning coffee as with an evening pour. The vintage floral relief and scalloped edge are designed purely for their beauty — a sculptural, ornamental detail that turns an ordinary tumbler into something quietly exceptional.
About the LUXE Collection
Each LUXE piece is a vintage-inspired silicone tumbler accessory designed as a sculptural finishing touch for your favorite cup — a 3D floral relief and a delicate scalloped edge, made purely to be beautiful. Designed and packed by hand in Castle Rock, Colorado.
