Neon is a bright orange.
#3 Nylon Coil Standard Zipper is 3mm across the closed coil & 1-1/16" wide side to side. Small, flexible but very strong.
Zipper heads (the part that opens & closes the tape) stocked in:
1) Shorts = the head or body is an auto-lock, or stops on the tape when you quit pulling, with a 5/8" long rectangular tab or pull. Best for pillows, duvet covers, little pouches & bags.
2) Longs = the head or body is a NON-lock, or just slides on the tape with a 1" rounded tab or pull. Best for pouches, bags, inside pockets, my "Old Lady" fingers.
Watch my videos to learn how to put the heads on head to head like backpack zippers.
Colors will vary from monitor to monitor. The "Samples" give you a 5" strip of zipper tape plus a header with color name & number.
