Question about drilling Topfin Tanks

[365seasons]

We just bought a 10G Topfin aquarium to use as a small species tank. We called the manufacturer and they told us that the bottom is acrylic but the sides are tempered glass.
Looking online at various forums and what not, we for the most part find that apparently in topfins, the sides are not tempered but the bottom is.

Contradictory, and confusing, as our tank is to be drilled through the bottom tomorrow morning.


Does anyone know any more on this, or could anyone shed some light on the situation??


Thanks in advance
