Is this bedding good/okay to use?

[WinnieTheHam]

I've been searching for a while now for a bedding that isn't dusty, and it seems to be recycled cardboard beddings to be the least. I've come across two different types, I'm just wondering has anyone used these before? and are they safe?

This is meant as a horse bedding, but I'm not entirely sure it'd be safe for hamsters - Zexum Clean Recycled Cardboard Shavings For Horse Bedding Packing | Free Delivery | Indoor Outdoor Electrical Security Heating Lighting Ventilation Cable | ElectricalEurope.com

This looks good, I'm just wondering if anyone has ever used it so I can have a second opinion before I buy - https://fetch.co.uk/pillow-wad-large...dl4aAgUS8P8HAQ
