As shown in pic, nice black and yellow combination. U I love Stanley products for their quality, durability and functionality. The product is strong and easy to hold. The lock mechanism is good but could have been better. Sometimes it doesn’t move up or down easily, gotta press more than one time for it to work. Useful for normal household work like tearing open cello tapes from parcels, which is why I bought them for. Even bubble wraps can be cut easily. Small cardboards can be cut too. ## Features - Ergonomic plastic frame, auto-locking - Supports up to 16.8 kg of force for cutting - Already comes with 1 blade of 15 cut-off points - Automatic blade lock, for safety - No blade cover at lower end for quick blade-change. - Package Contents: 1-Piece 18mm Snap Off Knife - Ideal for everyday DIY work with its robust and lightweight design - Limited Life time warranty offered on the product - The product is manufactured by Stanley Black & Decker with registered trademark ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07J4R74P5 | | Best Sellers Rank | #4,383 in Home Improvement ( See Top 100 in Home Improvement ) #32 in Utility Knives | | Blade Length | 18 Millimetres | | Blade Material | Carbon Steel | | Brand | STANLEY | | Brand Name | STANLEY | | Colour | Yellow | | Customer Reviews | 4.3 out of 5 stars 4,980 Reviews | | Handle Material | Plastic | | Handle Type | Auto-Retractable | | Importer Contact Information | Stanley Black & Decker India Private Ltd #28, Akemps, 3rd Main, 1st Cross, Ashwini Layout Koramangala Bangalore - 560047 | | Included Components | Package Contents: 1-Piece 18mm Snap Off Knife | | Item Length | 28 Centimetres | | Item Type Name | Plastic Slide Lock Snap-Off Knife | | Item Weight | 300 Grams | | Manufacturer | For any warranty related issues or product feedback, please feel free to contact us through our customer care number on: [ 1860-425-1111 ] between 10AM to 5PM from Monday to Friday (except government holidays), STANLEY | | Manufacturer Contact Information | For any warranty related issues or product feedback, please feel free to contact us through our customer care number on: [ 1860-425-1111 ] between 10AM to 5PM from Monday to Friday (except government holidays) | | Manufacturer Warranty Description | Limited Life time warranty for knife (Blade not included) | | Material | Plastic | | Material Type | Plastic | | Packer Contact Information | Stanley Black & Decker India Pvt Limited,GAT NO. 135. 137 & 157.
