Unopened and unused, this is a set of bed sheet elastic straps, JULKAKTUS, for use with IKEA bed pads, mattress protectors, and sheets. It includes 2 boxes, each containing 4 pieces. These were prepared for a photoshoot in the bedroom of a renovated 1SLDK apartment and are completely unopened and unused. The in-store & online price is ¥799 per box of 4 pieces (¥1598 for 2 boxes). Considering the round-trip transportation costs to the store and shipping fees for IKEA online, this is a good deal. Simply attach the straps to the four corners of your sheets, bed pads, or mattress protectors using the buckles! The straps are belt-style and adjustable in length. "My Experience" In my case, I have a high-resilience mattress topper on top of my mattress, and I use a mattress protector on top of the topper to keep the surface clean. The elastic on the four corners of the 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, are length-adjustable, and are very useful. A note of caution from 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 be careful. If the elastic on the four corners of your current bedding is worn out, you can simply replace the corners 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" 65% Polyester 35% Rubber "Care Instructions" Do not wash (Hand wash rubber parts only) Do not bleach Do not tumble dry Do not iron Do not dry clean
