## Description

desertcart.com : SPIDER CHALK Mega Gym Chalk Block, Lasts 2X Longer, Lab Grade | for Gym, Powerlifting, Made in The USA, ASMR : Sports & Outdoors

Review: Best chalk I’ve ever used - Chalk applies evenly and stays on. I use it for DL’s, shrugs, GM’s, pull up’s, etc. Does it’s job. Generous portion for the money. Made it the USA. Great customer service. Doesn’t smell bad at all. Yes, one of my blocks (you get two) had a small corner chip. I don’t mind because it saves me the trouble of making a mini chunk myself. Is it the manufacturer’s fault. No. It’s chalk. If desertcart didn’t package it in a bag and throw it around like a kickball- the chalk wouldn’t break. I got more than enough for my money- sending it back for being chipped would be silly. I use it for working out - not for drawing on the sidewalk.
Review: Excellent Product and Service - Service - Two of three blocks came slightly damaged, but there was a note in the box from Spider Chalk to let them know if the blocks had any damage and they would make it right. I emailed them, and got a quick response. They asked a couple questions about how the chalk was packaged, and they sent me three new replacement blocks perfectly packed, and completely damage free. That is outstanding service. Product - this chalk is great. It's very dense, so it doesn't break easily. I can tell I'll get more out of a block of Spider Chalk then a lot of the others out there because it doesn't keep breaking off small chunks that you can't use, and it doesn't dissolve into powder when applying it, which was the main thing I was looking for. I am completely satisfied with this product, and don't need to look for anything better.
