Some items have been opened, but they are new and unused. There are traces of stickers on the outer box. Gray 1.5m 【Industry's Highest Height, High-Type 30cm】We have improved the height to 30cm, a high-type design, compared to the conventional 24cm, incorporating the opinions of parenting mothers who want to reduce the possibility of falls and drops. *This product is not intended for use as a handrail, so it does not completely guarantee fall prevention. 【Improved Metal Stopper】Regarding the metal stopper that supports the cushion, other companies' metal stoppers only use fixing belts for support, but we have improved ours to a screw-fastening stopper to increase stability. *Please note that an electric screwdriver is required for screw fastening. 【Optional Fixing Belt Allows Installation Without Screws】We have developed a fixing belt for those who cannot screw the bed guard to the bed frame or who do not want to screw it. If you purchase a 2m or 1.8m bed guard, please use a set of 4 belts, and for a 1.5m bed guard, please use a set of 3 belts. 【Improved Washable High-Grade Velour Cover】We have made improvements based on valuable feedback from customers, such as "I want to wash the cover in the washing machine" due to "spit-up and stains." The cover is removable and can be easily washed in your home washing machine. Also, regarding the cover material, we compared and examined various samples such as mesh, cotton, linen, and brushed materials, and conducted a survey. We adopted a high-grade velour cover made of a brushed material that is gentle on the skin, even for delicate children. 【Added Water-Repellent Cover Inside】Inside the skin-friendly velour cover, we have added a water-repellent cover that can be cleaned with a quick wipe. "During the period of 0-1 year olds, there are many causes of stains, such as "spit-up" and "bedwetting." In such an event, we have added a water-repellent cover to protect the inner cushion.
