Excellent usability!! Popular bedding parts!! These are unopened boxes of JULKAKTUS (Yurukakutusu) bedding corner straps, perfect for bed pads, mattress protectors, and futon pads. Each box contains 4 pieces, and this listing includes 2 boxes. These were prepared for a photoshoot in the bedroom of a renovated 1SLDK apartment and are unopened. The in-store & online price is ¥799 per box of 4 pieces. Considering the round-trip transportation costs to the store and shipping fees from IKEA online, this is a great deal. Simply use the buckles on the straps to secure the corners of your sheets, bed pads, mattress protectors, etc.! The straps are belt-style and adjustable in length. ※ Image 4 shows the same product being used in my home. At home, I have a high-resilience mattress on top of my mattress, and to keep the surface clean, I put a mattress protector on top of the high-resilience mattress. The elastic corners on that protector had stretched out, so I cut them off at the base and started using these straps to secure it. They don't come off easily and are very useful. A note of caution based on my experience: If you wash the bedding with the straps attached because it's a hassle, the metal parts of the buckles may rust, so please be careful. If only the elastic corners of your current bedding are worn out, you can simply replace them with these straps instead of buying new bedding! 【Product Details】 "Official Search No." 703.982.90 "Product Size" Width → 10cm Height → 2cm Length → 16cm Weight → 0.09g "Length Adjustment Function" Yes "Material" Polyester 65% Rubber 35% "Care Instructions" Do not wash (Hand wash rubber parts only) Do not bleach Do not tumble dry Do not iron Do not dry clean
