This is an Aller Guard box sheet. ■ New, unused ■ Color: Brown ■ Size: Queen (160 x 200 x 30 cm) ■ Elasticized all around the back ■ Material: 80% Polyester, 20% Cotton This type uses a high-density fabric to prevent the entry of dust mites, dust, and pollen. Since no chemicals are used, it can be safely used by those who sleep with small children or pets. For shipping purposes, I plan to open the package just before shipping, remove the cardboard insert (core material), and fold it compactly for packaging. *Creases may form. The product itself is unused. Thank you to those who understand home storage and shipping methods. Immediate purchase is OK! *The shipping method may be changed between RakuRaku Mercari便 and YuuYuu Mercari便.
