This item features a strong suction cup and support plate, eliminating the need for a triangular corner strainer, and comes with 40 dedicated bags for easy washing. - Brand: DAICEL - Product Name: No Triangular Corner Strainer Needed - Features: Easy to wash, strong suction cup, with support plate - Quantity: 1 main unit (with 5 dedicated bags) + 40 dedicated bags Thank you for viewing. I purchased this intending to use it, but I never did, so I am now offering it for sale. It is a new, unused item. The adhesive area of the outer packaging for the dedicated bags has a stain (see photo 6), so I have cut it off and secured it with tape for shipping, but the item itself is unused. Please review the photo descriptions and understand that this item has been stored at home before purchasing. Thank you for your consideration.
