Thank you for viewing. This is a 4-tier "Mega Tuff Tray" set from SONIC. It's a durable document tray, convenient for organizing A4-size documents and Kakuni (No. 2) envelopes. Made with reinforced plastic (polycarbonate) also used in suitcases, it's resistant to cracking and built to last. 【Product Details】 ・Manufacturer: SONIC ・Model Number: DA-2658-CB ・Color: Clear Blue ・Number of Tiers: 4 tiers (4 trays) ・Size (per tier): Outer dimensions approximately 260 x 340 x 65mm ・Compatible Sizes: A4, Kakuni (No. 2) envelopes ・Material: Polycarbonate 【Condition】 It has been used, but the frequency of use was low. There are no noticeable scratches or cracks, but please understand that it is a used item, so there may be minor scuffs. 【Other】 Please refrain from purchasing if you are sensitive to used items, as it has been stored at home. I am not considering selling individual trays. It will be sold as a set of 4 tiers. Thank you!
