Balance cushion perfect for core training at home or in the office. - Brand: COREBLADE - Product Name: BALANCE CUSHION - Color: Black - Training Method: Core Training - Included: Pump, Memo I bought this to train my child's core, but it has only been used for short periods about 3 times and has been left unused since. There are some scuff marks on the smooth surface. I have disinfected the entire product with alcohol and wiped it with cotton swabs, but there may be some small remaining dirt that I couldn't remove. Please understand this before purchasing. Please refrain from price reduction requests due to the size. Shipped anonymously with the option for unattended delivery. I will reuse the brown paper used for cushioning and wrap it so that the box is not visible. Thank you for viewing.
