Great value, lots of fun to go through, the extra pamphlet with info on each of the packs was a great addition.

I’ve bought a few boxes from Arthur’s now and have been genuinely impressed with the quality, pricing, and timeliness of every order. Will definitely be buying more from them in the future!

The roundup box was priced very fairly, showed up quick, and was in great shape. Pulled some big hits out of the box too. Had a great experience shopping at Arthur’s and will be buying from them again!
