Size 6" L x 5.5" H x 2" D (open) We have been known for our treat bags since we first opened our doors 16 years ago. Our newest Trek & Train model has been updated to include a magnetic closure and is made with 600 D ("backpack") fabric. Our superior quality and design make this a bait bag that will last through who knows how many dogs! Attaches with a clip, includes loops if you prefer to thread a belt (OPTIONAL BELT ADD ON $2.75). Features include: Magnetic closure with pull tab for easy open/close. Front pocket 4" W x 3" H with a Velcro closure. Roomy enough to hold various types of clickers, pickup bags or special bait, it keeps its shape and looks attractive if left empty. Zipper down one side creates a roomy compartment out of the entire back panel. Grey interior liner for improved visibility (wipes clean). D-ring on side for attaching leads or training items. Sturdy custom-made belt clip, as well as loops to thread a belt. Constructed of 600 denier poly cloth. Machine washable, cool or warm water. Line dry. Do not use bleach. We do not recommend putting these in the dishwasher.
