The Toyo-Sasaki Handcrafted Seiro Tableware Collection brings together subtle elegance and natural beauty through hand-finished glassware that evokes the quiet clarity of early morning dew. The word “Seiro” (清露せいろ) means “pure dew,” and each piece captures that sense with soft gradients of misty blue and a rippling texture reminiscent of water’s surface.
From small side dishes to serving bowls, this collection is designed to elevate both everyday dining and special moments. Whether you are serving chilled noodles, sashimi, fresh fruit, or seasonal appetizers, the Seiro Collection adds a gentle visual poetry to your presentation.
Each piece is made in Japan using traditional techniques and carefully finished for both durability and aesthetic harmony. Seiro tableware embodies a quiet sophistication that pairs beautifully with both modern and traditional settings.
