Other
About washing the cover
・Please hand wash when washing.
・After washing, smooth out any wrinkles in the four corners, reshape, and dry in the shade.
※Please avoid using a washing machine, as it may cause damage to the fabric or shrinkage.

About bead flattening
・The expanded beads in the filling are made to resist flattening, but flattening may occur due to usage period, condition, and aging.
※Refill beads (20L/bag) are sold separately. Please inquire if needed.

About the fabric
・The tetra No. 8 canvas uses water-repellent treated canvas fabric. During the manual cover-setting process, friction or folding of the fabric may cause some parts to turn white. This is due to the water-repellent agent and starch for stiffness, and is a characteristic of No. 8 canvas fabric (chalk marks).
・Canvas fabric may contain slubs, which are knots in the yarn, on the fabric surface during the manufacturing process. Please enjoy this as a natural characteristic of the material.
