Love the packaging, love the tropical mix and will order more in the future 🥰
So just got the megamix. My first impression is that soil is a wonderful organic mix. You can see, smell and feel the difference in this substrate compared to any others ive used. I really love that a complete list of ingredients is given. I fully believe this will be a great mix for my bioactive enclosure in the long run.
The product is great! I love the substrate and will be ordering more.
Dark and heavy, but also fine. I hate getting tropical soil with huge charcoal chunks and whatnot. Also appreciate that this comes premixed, less mess.
The tropical substrate is perfect for the tarantula species I have that prefer more humidity than my other species.
The tropical substrate holds the burrows and moisture well, and I’ve yet to have any issues with molding, with the occasional mistings or corner waterings I do. I definitely recommend.

Phenomenal customer service! Spiderlings are healthy and active, packaged great and arrived perfect. Will definitely be ordering again in the future!

I received my C.versicolor today and I couldn’t be happier! My little sling was healthy and well packaged. Customer service is excellent as well! Definitely ordering from Marshall arachnids again!

Spider arrived healthy and was packaged safely! 10/10

Wonderful quality!! Spider arrived healthy and was packaged safely! 10/10

Purchasing and scheduling pickup were straightforward. No customer service concerns. Spiders arrived well packaged and with a temperature packet. Each also had a hatch date card and serial number. Both spiders were lively and readily rehoused. They've both made little nets when hungry. Will definitely purchase from Marshall's again!!

As i opened the vials they came in they were super active and nice size they looked well taken care of can't wait to get some other Ts

I am pleased with my experience dealing with Marshall Arachnids. Customer service is good and they respond to any questions and conserns quickly.

Excellent made enclosure!! And healthy ogre faced spider!
Great customer service and will be ordering from here again!!!

Shes an amazing spood! Marshall called and scheduled delivery with me to a nearby fedex location to ensure Gwen was only traveling as short a time as possible. She left Marshall at like 4pm and arrived at my loval fedex by 7am the next morning. They definitely have the health and wellness of the animal at the front of their mind

The only difficult part is actually deciding what to pick! Great communication the entire time. All vials were packaged perfectly. All slings were healthy and settling in well. Thanks guys!

These little guys are awesome arrived healthy and well started

These folks are the nicest, most genuine and knowledgeable people in the hobby (at least that I know of). Anytime I have had questions, one of them is always quick to get back to me. Lastly, their animals are top notch. Every one i have bought from them is thriving and beautiful. Thanks again Marshall's!
They are so cool and interesting there web work is amazing

We just purchased our first Marshall Tarantula Crib the quality is striking. I love the purple color, but the construction is fantastic. Super strong magnets, beefy panels, and great air flow. I will be back. Wow!
